<statusp>This is a W3C Working Draft for review by W3C members and other
interested parties. It is a draft document and may be updated,
replaced, or obsoleted by other documents at any time. It is
inappropriate to use W3C Working Drafts as reference material or to
cite them as other than "work in progress". A list of current W3C
working drafts can be found at
<loc href="http://www.w3.org/TR">http://www.w3.org/TR</loc>.</statusp>
<statusp><emph>Note:</emph> Since working drafts are subject to frequent
change, you are advised to reference the above URL, rather than the

<statusp>This work is part of the W3C SGML Activity (for current
status, see <loc href="http://www.w3.org/MarkUp/SGML/Activity"

<p>The current
draft of this specification
presupposes the successful completion of the current
work on the &WebSGML;, being prepared by ISO/IEC JTC1
at the time this draft specification was drafted.
If it is not
adopted in the expected form, some clauses of this specification
may change, and some
recommendations now labeled "<termref def="dt-interop">for
interoperability</termref>" will become requirements labeled
"<termref def="dt-compat">for compatibility</termref>".
</p>
<p>The current draft of this specification uses the term
URI, which is defined by
<bibref ref="Berners-Lee"/>,
which is work in progress expected to update
<bibref ref="RFC1738"/> and <bibref ref="RFC1808"/>.
Should the work in this draft not be accepted as an RFC, the
references to uniform resource identifiers (URIs) in this
specification will become references to uniform resource
locators (URLs).</p>

<sitem>1997-12-03 : CMSMcQ : yet further changes</sitem>
<sitem>1997-12-02 : TB : further changes (see TB to XML WG,
2 December 1997)</sitem>
<sitem>1997-12-02 : CMSMcQ : deal with as many corrections and
comments from the proofreaders as possible:
entify hard-coded document date in pubdate element,
change expansion of entity WebSGML,
update status description as per Dan Connolly (am not sure
about refernece to Berners-Lee et al.),
add 'The' to abstract as per WG decision,
move Relationship to Existing Standards to back matter and
combine with References,
re-order back matter so normative appendices come first,
re-tag back matter so informative appendices are tagged informdiv1,
remove XXX XXX from list of 'normative' specs in prose,
move some references from Other References to Normative References,
add RFC 1738, 1808, and 2141 to Other References (they are not
normative since we do not require the processor to enforce any
rules based on them),
add reference to 'Fielding draft' (Berners-Lee et al.),
move notation section to end of body,
drop URIchar non-terminal and use SkipLit instead,
lose stray reference to defunct nonterminal 'markupdecls',
move reference to Aho et al. into appendix (Tim's right),
add prose note saying that hash marks and fragment identifiers are
NOT part of the URI formally speaking, and are NOT legal in
system identifiers (processor 'may' signal an error).
Work through:
Tim Bray reacting to James Clark,
Tim Bray on his own,
Eve Maler,
NOT DONE YET:
change binary / text to unparsed / parsed.
handle James's suggestion about < in attriubte values
uppercase hex characters,
namechar list,
</sitem>
<sitem>1997-12-01 : JB : add some column-width parameters</sitem>
<sitem>1997-12-01 : CMSMcQ : begin round of changes to incorporate
recent WG decisions and other corrections:
binding sources of character encoding info (27 Aug / 3 Sept),
correct wording of Faust quotation (restore dropped line),
drop SDD from EncodingDecl,
change text at version number 1.0,
drop misleading (wrong!) sentence about ignorables and extenders,
modify definition of PCData to make bar on msc grammatical,
change grammar's handling of internal subset (drop non-terminal markupdecls),
change definition of includeSect to allow conditional sections,
add integral-declaration constraint on internal subset,
drop misleading / dangerous sentence about relationship of
entities with system storage objects,
change table body tag to htbody as per EM change to DTD,
add rule about space normalization in public identifiers,
add description of how to generate our name-space rules from
Unicode character database (needs further work!).
</sitem>
<sitem>1997-10-08 : TB : Removed %-constructs again, new rules
for PE appearance.</sitem>
<sitem>1997-10-01 : TB : Case-sensitive markup; cleaned up
element-type defs, lotsa little edits for style</sitem>
<sitem>1997-09-25 : TB : Change to elm's new DTD, with
substantial detail cleanup as a side-effect</sitem>
<sitem>1997-07-24 : CMSMcQ : correct error (lost *) in definition
of ignoreSectContents (thanks to Makoto Murata)</sitem>
<sitem>Allow all empty elements to have end-tags, consistent with
SGML TC (as per JJC).</sitem>
<sitem>1997-07-23 : CMSMcQ : pre-emptive strike on pending corrections:
introduce the term 'empty-element tag', note that all empty elements
may use it, and elements declared EMPTY must use it.
Add WFC requiring encoding decl to come first in an entity.
Redefine notations to point to PIs as well as binary entities.
Change autodetection table by removing bytes 3 and 4 from
examples with Byte Order Mark.
Add content model as a term and clarify that it applies to both
mixed and element content.
</sitem>
<sitem>1997-06-30 : CMSMcQ : change date, some cosmetic changes,
changes to productions for choice, seq, Mixed, NotationType,
Enumeration. Follow James Clark's suggestion and prohibit
conditional sections in internal subset. TO DO: simplify
production for ignored sections as a result, since we don't
need to worry about parsers which don't expand PErefs finding
a conditional section.</sitem>
<sitem>1997-06-29 : TB : various edits</sitem>
<sitem>1997-06-29 : CMSMcQ : further changes:
Suppress old FINAL EDIT comments and some dead material.
Revise occurrences of % in grammar to exploit Henry Thompson's pun,
especially markupdecl and attdef.
Remove RMD requirement relating to element content (?).
</sitem>
<sitem>1997-06-28 : CMSMcQ : Various changes for 1 July draft:
Add text for draconian error handling (introduce
the term Fatal Error).
RE deleta est (changing wording from
original announcement to restrict the requirement to validating
parsers).
Tag definition of validating processor and link to it.
Add colon as name character.
Change def of %operator.
Change standard definitions of lt, gt, amp.
Strip leading zeros from #x00nn forms.</sitem>
<sitem>1997-04-02 : CMSMcQ : final corrections of editorial errors
found in last night's proofreading. Reverse course once more on
well-formed: Webster's Second hyphenates it, and that's enough
for me.</sitem>
<sitem>1997-04-01 : CMSMcQ : corrections from JJC, EM, HT, and self</sitem>
<sitem>1997-03-31 : Tim Bray : many changes</sitem>
<sitem>1997-03-29 : CMSMcQ : some Henry Thompson (on entity handling),
some Charles Goldfarb, some ERB decisions (PE handling in miscellaneous
declarations. Changed Ident element to accept def attribute.
Allow normalization of Unicode characters. move def of systemliteral
into section on literals.</sitem>
<sitem>1997-03-28 : CMSMcQ : make as many corrections as possible, from
Terry Allen, Norbert Mikula, James Clark, Jon Bosak, Henry Thompson,
Paul Grosso, and self. Among other things: give in on "well formed"
(Terry is right), tentatively rename QuotedCData as AttValue
and Literal as EntityValue to be more informative, since attribute
values are the <emph>only</emph> place QuotedCData was used, and
vice versa for entity text and Literal. (I'd call it Entity Text,
but 8879 uses that name for both internal and external entities.)</sitem>
<sitem>1997-03-26 : CMSMcQ : resynch the two forks of this draft, reapply
my changes dated 03-20 and 03-21. Normalize old 'may not' to 'must not'
except in the one case where it meant 'may or may not'.</sitem>
<sitem>1997-03-21 : TB : massive changes on plane flight from Chicago
to Vancouver</sitem>
<sitem>1997-03-21 : CMSMcQ : correct as many reported errors as possible.
</sitem>
<sitem>1997-03-20 : CMSMcQ : correct typos listed in CMSMcQ hand copy of spec.</sitem>
<sitem>1997-03-20 : CMSMcQ : cosmetic changes preparatory to revision for
WWW conference April 1997: restore some of the internal entity
references (e.g. to docdate, etc.), change character xA0 to &nbsp;
and define nbsp as &#160;, and refill a lot of paragraphs for
legibility.</sitem>
<sitem>1996-11-12 : CMSMcQ : revise using Tim's edits:
Add list type of NUMBERED and change most lists either to
BULLETS or to NUMBERED.
Suppress QuotedNames, Names (not used).
Correct trivial-grammar doc type decl.
Rename 'marked section' as 'CDATA section' passim.
Also edits from James Clark:
Define the set of characters from which [^abc] subtracts.
Charref should use just [0-9] not Digit.
Location info needs cleaner treatment: remove? (ERB
question).
One example of a PI has wrong pic.
Clarify discussion of encoding names.
Encoding failure should lead to unspecified results; don't
prescribe error recovery.
Don't require exposure of entity boundaries.
Ignore white space in element content.
Reserve entity names of the form u-NNNN.
Clarify relative URLs.
And some of my own:
Correct productions for content model: model cannot
consist of a name, so "elements ::= cp" is no good.
</sitem>
<sitem>1996-11-11 : CMSMcQ : revise for style.
Add new rhs to entity declaration, for parameter entities.</sitem>
<sitem>1996-11-10 : CMSMcQ : revise for style.
Fix / complete section on names, characters.
Add sections on parameter entities, conditional sections.
Still to do: Add compatibility note on deterministic content models.
Finish stylistic revision.</sitem>
<sitem>1996-10-31 : TB : Add Entity Handling section</sitem>
<sitem>1996-10-30 : TB : Clean up term & termdef. Slip in
ERB decision re EMPTY.</sitem>
<sitem>1996-10-28 : TB : Change DTD. Implement some of Michael's
suggestions. Change comments back to //. Introduce language for
XML namespace reservation. Add section on white-space handling.
Lots more cleanup.</sitem>
<sitem>1996-10-24 : CMSMcQ : quick tweaks, implement some ERB
decisions. Characters are not integers. Comments are /* */ not //.
Add bibliographic refs to 10646, HyTime, Unicode.
Rename old Cdata as MsData since it's <emph>only</emph> seen
in marked sections. Call them attribute-value pairs not
name-value pairs, except once. Internal subset is optional, needs

<!--* N.B. some readers (notably JC) find the following

it *says* it is summarizing the logical implications of
matching the grammar, and that means by definition it's
logically redundant. I don't think it's rhetorically
redundant or unnecessary, though, so I'm keeping it. It

stronger. -MSM *-->

<!--
This is not quite right: < should be legal, should it not?

<!-- Henry Thompson suggests (in substance, not form: the wording needs
to be clarified):
"Cooked Attribute values must not contain < & or the
quote which closed their uncooked literal,
unless arising from the expansion of a character reference or
magic reference
directly contained in their uncooked literal."
I'm not sure I agree with this rule, but it's at least coherent,
which is more than I can say for my attempt.

logical structure.

<div3 id='gen-char-entproc'>
<head>General and Character Entity Processing</head>
<p>General-entity and character references are recognized in three
contexts: wherever the nonterminal <nt def='NT-content'>content</nt> may
appear, at any point within the nonterminal
<nt def='NT-AttValue'>AttValue</nt>,
and within the
<termref def='dt-litentval'>literal entity value</termref>
(<nt def='NT-EntityValue'>EntityValue</nt>)
of an internal entity declaration.
This section discusses the first two cases; the third
is discussed <titleref href='intern-replacement'>below</titleref>.
When an <termref def="dt-xml-proc">XML processor</termref> encounters
such a reference, or the name of an unparsed entity as the value
of an <kw>ENTITY</kw> or <kw>ENTITIES</kw> attribute, then:
<olist>
<item><p>In all cases, the XML processor may
inform the application of the reference's occurrence and its identifier
(for an entity reference, the name; for a character
reference,
the character number in decimal, hexadecimal, or binary form).</p></item>
<item><p>For both character and entity references, the processor must
remove the reference itself from the <termref def="dt-text">text</termref> data
before passing the data to the application.
</p></item>
<item><p>For character references, the processor must
pass the character indicated
to the application in
place of the reference.
</p></item>
<item><p>For an external entity, the processor must inform the
application of the entity's <termref def="dt-sysid">system
identifier</termref>, and <termref def="dt-pubid">public identifier</termref>
if any.
All strings
of white space in the public identifier must be normalized to single space characters (#x20),
and leading and trailing white space must be removed.</p></item>
<item><p>If the external entity is binary, the processor must inform the
application of the associated <termref def="dt-notation">notation</termref>
name, and the notation's associated <termref def='dt-sysid'>system</termref>
and <termref def='dt-pubid'>public</termref> (if any)
identifiers.</p></item>
<item><p><termdef id="dt-include" term="Include">For an internal
(parsed) entity, the processor must <term>include</term> the
entity; that is, retrieve its replacement text
and process it as a part of the document
(i.e. as <nt def="NT-content">content</nt> or <nt
def="NT-AttValue">AttValue</nt>, whichever was being processed when
the reference was recognized), passing the result to the application
in place of the reference. The replacement text may contain both
<termref def='dt-chardata'>character data</termref>
and <termref def="dt-markup">markup</termref>, which must be recognized in
the usual way, except that the replacement text of entities used to escape
markup delimiters (the entities &magicents;) is always treated as
data. (The string "<code>AT&amp;T;</code>" expands to
"<code>AT&T;</code>" since the ampersand replacing "<code>&amp;</code>"
is not recognized
as an entity-reference delimiter.) </termdef></p>
<p>Since the entity may contain other entity references,
an XML processor may have to repeat the inclusion process recursively.</p>
</item>
<item><p>If the entity is an external parsed entity, then in order to
<termref def="dt-valid">validate</termref> the XML document, the processor must
<termref def="dt-include">include</termref> the content of the
entity.</p></item>
<item><p>If the entity is an external parsed entity, and the processor is not
attempting to <termref def="dt-valid">validate</termref> the XML document, the
processor <termref def="dt-may">may</termref>, but need not, <termref
def="dt-include">include</termref> the entity's content.</p>
<p>This rule is based on the recognition that the automatic inclusion
provided by the SGML and XML entity mechanism, primarily designed
to support modularity in authoring, is not necessarily
appropriate for other applications, in particular document browsing.
Browsers, for example, when encountering an external parsed entity reference,
might choose to provide a visual indication of the entity's
presence and retrieve it for display only on demand.
</p></item>
</olist>
</p>
<p><termdef id="dt-escape" term="escape">Entity and character
references can both be used to <term>escape</term> the left angle bracket,
ampersand, and other delimiters. A set of general entities
(&magicents;) is specified for this purpose.
Numeric character references may also be used; they are
expanded immediately when recognized, and must be treated as
character data, so the numeric character references
"<code>&#60;</code>" and "<code>&#38;</code>" may be used to
escape <code><</code> and <code>&</code> when they occur
in character data.</termdef></p>
</div3>
<div3 id='PE-proc'>
<head>Parameter Entity Processing</head>
<p>Parameter-entity references are only recognized in the
<termref def='dt-doctype'>DTD</termref>.
Their processing, when they appear
within the
<termref def='dt-litentval'>literal entity value</termref>
(<nt def='NT-EntityValue'>EntityValue</nt>)
of an internal entity declaration,
is discussed <titleref href='intern-replacement'>below</titleref>.
They have these intended uses:
<olist>
<item><p>as a replacement for one or more complete markup declarations</p></item>
<item><p>as a replacement for one or more complete "groups" in
element declarations</p></item>
<item><p>as a replacement for one or more complete "tokens" in
markup declarations</p></item>
</olist>
</p>
<p>The constraints requiring that PE replacement texts be properly nested
with <titleref href='vc-PEinMarkupDecl'>markup declarations</titleref>
and <titleref href='vc-PEinGroup'>content groups</titleref>
govern the first two usages.</p>
<p>To support the third intended usage,
when an XML processor encounters a parameter-entity reference
(outside of the
<termref def='dt-litentval'>literal entity value</termref> in an entity
declaration),
it must <termref def="dt-include">include</termref>
the named entity, but first expand its
<termref def='dt-repltext'>replacement text</termref> by attaching
space (#x20) characters to its beginning and the end, before
processing it.</p>
<p>The DTD text must match the relevant
rules of this specification's grammar after all parameter-entity
references have been expanded.
<!-In addition, parameter entities referred to in specific
contexts are required to satisfy certain constraints in their
replacement text; for example, a parameter entity referred to within
the internal DTD subset must match the rule for <nt
def="NT-markupdecl">markupdecl</nt>. ->

<!-- Replaced by the above -TB
<p>Implementors of XML processors need to know the rules for
expansion of references in more detail. These rules only come into
play when the replacement text for an internal entity itself contains
other references.
<olist>
<item><p>In the replacement text of an internal entity, parameter-entity
references and character references in the replacement text
are recognized and resolved
when the entity declaration is parsed,
before the replacement text is stored in
the processor's symbol table.
General-entity references in the replacement text are not
resolved when the entity declaration is parsed.</p></item>
<item><p>In the document, when a general-entity reference is
resolved, its replacement text is parsed. Character references
encountered in the replacement text are
resolved immediately; general-entity references encountered in the
replacement text may be resolved or left unresolved, as described
<titleref href="entproc">above</titleref>.
Character and general-entity references must be
contained entirely within the entity's replacement text.
</p></item>
</olist>
</p>
<p>Simple character references do not suffice to escape delimiters
within the replacement text of an internal entity: they will be
expanded when the entity declaration is parsed, before the replacement
text is stored in the symbol table. When the entity itself is
referred to, the replacement text will be parsed again, and the
delimiters (no longer character references)
will be recognized as delimiters. To escape the
characters &magicents; in an entity replacement text, use
a general-entity reference or a doubly-escaped character reference.
See <titleref href='sec-entexpand'>the appendix on expansion
of entity references</titleref>
for detailed examples.</p>

<def><p>specifies that <emph>in the external DTD subset</emph> a
<termref def='dt-param-entity'>parameter entity</termref> may occur in the
text at the position where <code>a</code> may occur; if so, its
replacement text must match <code>S? a S?</code>. If
the expression <code>a</code> is governed by a suffix operator, then
the suffix operator determines both the maximum number of parameter-entity
references allowed and the number of occurrences of <code>a</code>
in the replacement text of the parameter entities: <code>%a*</code>
means that <code>a</code> must occur zero or more times, and
that some of its occurrences may be replaced by references to
parameter entities whose replacement text must contain zero or
more occurrences of <code>a</code>; it is thus a more compact way
of writing <code>%(a*)*</code>.
Similarly, <code>%a+</code> means that <code>a</code>
must occur one or more times, and may be replaced by
parameter entities with replacement text matching
<code>S? (a S?)+</code>.
The recognition of parameter entities in the internal subset is much more
highly constrained.

A very simple, though non-conforming, <termref def="dt-xml-proc">XML
