   290 <p>The current

   291 draft of this specification 

   292 presupposes the successful completion of the current

   293 work on the &WebSGML;, being prepared by ISO/IEC JTC1 

   294 at the time this draft specification was drafted.

   295 If it is not

   296 adopted in the expected form, some clauses of this specification 

   297 may change,  and some

   298 recommendations now labeled "<termref def="dt-interop">for

   299 interoperability</termref>" will become requirements labeled

   300 "<termref def="dt-compat">for compatibility</termref>".

   301 </p>

   302 <p>The current draft of this specification uses the term 

   303 URI, which is defined by 

   304 <bibref ref="Berners-Lee"/>,

   305 which is work in progress expected to update 

   306 <bibref ref="RFC1738"/> and <bibref ref="RFC1808"/>.

   307 Should the work in this draft not be accepted as an RFC, the

   308 references to uniform resource identifiers (URIs) in this

   309 specification will become references to uniform resource

   310 locators (URLs).</p>

   329 <sitem>1997-12-02 : TB : further changes (see TB to XML WG,

   330 2 December 1997)</sitem>

   331 <sitem>1997-12-02 : CMSMcQ : deal with as many corrections and

   332 comments from the proofreaders as possible:

   333 entify hard-coded document date in pubdate element,

   334 change expansion of entity WebSGML,

   335 update status description as per Dan Connolly (am not sure

   336 about refernece to Berners-Lee et al.),

   337 add 'The' to abstract as per WG decision,

   338 move Relationship to Existing Standards to back matter and

   339 combine with References,

   340 re-order back matter so normative appendices come first,

   341 re-tag back matter so informative appendices are tagged informdiv1,

   342 remove XXX XXX from list of 'normative' specs in prose,

   343 move some references from Other References to Normative References,

   344 add RFC 1738, 1808, and 2141 to Other References (they are not

   345 normative since we do not require the processor to enforce any 

   346 rules based on them),

   347 add reference to 'Fielding draft' (Berners-Lee et al.),

   348 move notation section to end of body,

   349 drop URIchar non-terminal and use SkipLit instead,

   350 lose stray reference to defunct nonterminal 'markupdecls',

   351 move reference to Aho et al. into appendix (Tim's right),

   352 add prose note saying that hash marks and fragment identifiers are

   353 NOT part of the URI formally speaking, and are NOT legal in 

   354 system identifiers (processor 'may' signal an error).

   355 Work through:

   356 Tim Bray reacting to James Clark,

   357 Tim Bray on his own,

   358 Eve Maler,

   359 

   360 NOT DONE YET:

   361 change binary / text to unparsed / parsed.

   362 handle James's suggestion about < in attriubte values

   363 uppercase hex characters,

   364 namechar list,

   365 </sitem>

   366 <sitem>1997-12-01 : JB : add some column-width parameters</sitem>

   367 <sitem>1997-12-01 : CMSMcQ : begin round of changes to incorporate

   368 recent WG decisions and other corrections:

   369 binding sources of character encoding info (27 Aug / 3 Sept),

   370 correct wording of Faust quotation (restore dropped line),

   371 drop SDD from EncodingDecl,

   372 change text at version number 1.0,

   373 drop misleading (wrong!) sentence about ignorables and extenders,

   374 modify definition of PCData to make bar on msc grammatical,

   375 change grammar's handling of internal subset (drop non-terminal markupdecls),

   376 change definition of includeSect to allow conditional sections,

   377 add integral-declaration constraint on internal subset,

   378 drop misleading / dangerous sentence about relationship of

   379 entities with system storage objects,

   380 change table body tag to htbody as per EM change to DTD,

   381 add rule about space normalization in public identifiers,

   382 add description of how to generate our name-space rules from 

   383 Unicode character database (needs further work!).

   384 </sitem>

   385 <sitem>1997-10-08 : TB : Removed %-constructs again, new rules

   386 for PE appearance.</sitem>

   387 <sitem>1997-10-01 : TB : Case-sensitive markup; cleaned up

   388 element-type defs, lotsa little edits for style</sitem>

   389 <sitem>1997-09-25 : TB : Change to elm's new DTD, with

   390 substantial detail cleanup as a side-effect</sitem>

   391 <sitem>1997-07-24 : CMSMcQ : correct error (lost *) in definition 

   392 of ignoreSectContents (thanks to Makoto Murata)</sitem>

   393 <sitem>Allow all empty elements to have end-tags, consistent with

   394 SGML TC (as per JJC).</sitem>

   395 <sitem>1997-07-23 : CMSMcQ : pre-emptive strike on pending corrections:

   396 introduce the term 'empty-element tag', note that all empty elements

   397 may use it, and elements declared EMPTY must use it.

   398 Add WFC requiring encoding decl to come first in an entity.

   399 Redefine notations to point to PIs as well as binary entities.

   400 Change autodetection table by removing bytes 3 and 4 from 

   401 examples with Byte Order Mark.

   402 Add content model as a term and clarify that it applies to both

   403 mixed and element content.

   404 </sitem>

   405 <sitem>1997-06-30 : CMSMcQ : change date, some cosmetic changes,

   406 changes to productions for choice, seq, Mixed, NotationType,

   407 Enumeration.  Follow James Clark's suggestion and prohibit 

   408 conditional sections in internal subset.  TO DO:  simplify

   409 production for ignored sections as a result, since we don't 

   410 need to worry about parsers which don't expand PErefs finding

   411 a conditional section.</sitem>

   412 <sitem>1997-06-29 : TB : various edits</sitem>

   413 <sitem>1997-06-29 : CMSMcQ : further changes:

   414 Suppress old FINAL EDIT comments and some dead material.

   415 Revise occurrences of % in grammar to exploit Henry Thompson's pun,

   416 especially markupdecl and attdef.

   417 Remove RMD requirement relating to element content (?).

   418 </sitem>

   419 <sitem>1997-06-28 : CMSMcQ : Various changes for 1 July draft:

   420 Add text for draconian error handling (introduce

   421 the term Fatal Error).

   422 RE deleta est (changing wording from 

   423 original announcement to restrict the requirement to validating

   424 parsers).

   425 Tag definition of validating processor and link to it.

   426 Add colon as name character.

   427 Change def of %operator.

   428 Change standard definitions of lt, gt, amp.

   429 Strip leading zeros from #x00nn forms.</sitem>

   430 <sitem>1997-04-02 : CMSMcQ : final corrections of editorial errors

   431 found in last night's proofreading.  Reverse course once more on

   432 well-formed:   Webster's Second hyphenates it, and that's enough

   433 for me.</sitem>

   434 <sitem>1997-04-01 : CMSMcQ : corrections from JJC, EM, HT, and self</sitem>

   435 <sitem>1997-03-31 : Tim Bray : many changes</sitem>

   436 <sitem>1997-03-29 : CMSMcQ : some Henry Thompson (on entity handling),

   437 some Charles Goldfarb, some ERB decisions (PE handling in miscellaneous

   438 declarations.  Changed Ident element to accept def attribute.

   439 Allow normalization of Unicode characters.  move def of systemliteral

   440 into section on literals.</sitem>

   441 <sitem>1997-03-28 : CMSMcQ : make as many corrections as possible, from

   442 Terry Allen, Norbert Mikula, James Clark, Jon Bosak, Henry Thompson,

   443 Paul Grosso, and self.  Among other things:  give in on "well formed"

   444 (Terry is right), tentatively rename QuotedCData as AttValue

   445 and Literal as EntityValue to be more informative, since attribute

   446 values are the <emph>only</emph> place QuotedCData was used, and

   447 vice versa for entity text and Literal. (I'd call it Entity Text, 

   448 but 8879 uses that name for both internal and external entities.)</sitem>

   449 <sitem>1997-03-26 : CMSMcQ : resynch the two forks of this draft, reapply

   450 my changes dated 03-20 and 03-21.  Normalize old 'may not' to 'must not'

   451 except in the one case where it meant 'may or may not'.</sitem>

   452 <sitem>1997-03-21 : TB : massive changes on plane flight from Chicago

   453 to Vancouver</sitem>

   454 <sitem>1997-03-21 : CMSMcQ : correct as many reported errors as possible.

   455 </sitem>

   456 <sitem>1997-03-20 : CMSMcQ : correct typos listed in CMSMcQ hand copy of spec.</sitem>

   457 <sitem>1997-03-20 : CMSMcQ : cosmetic changes preparatory to revision for

   458 WWW conference April 1997:  restore some of the internal entity 

   459 references (e.g. to docdate, etc.), change character xA0 to  

   460 and define nbsp as  , and refill a lot of paragraphs for

   461 legibility.</sitem>

   462 <sitem>1996-11-12 : CMSMcQ : revise using Tim's edits:

   463 Add list type of NUMBERED and change most lists either to

   464 BULLETS or to NUMBERED.

   465 Suppress QuotedNames, Names (not used).

   466 Correct trivial-grammar doc type decl.

   467 Rename 'marked section' as 'CDATA section' passim.

   468 Also edits from James Clark:

   469 Define the set of characters from which [^abc] subtracts.

   470 Charref should use just [0-9] not Digit.

   471 Location info needs cleaner treatment:  remove?  (ERB

   472 question).

   473 One example of a PI has wrong pic.

   474 Clarify discussion of encoding names.

   475 Encoding failure should lead to unspecified results; don't

   476 prescribe error recovery.

   477 Don't require exposure of entity boundaries.

   478 Ignore white space in element content.

   479 Reserve entity names of the form u-NNNN.

   480 Clarify relative URLs.

   481 And some of my own:

   482 Correct productions for content model:  model cannot

   483 consist of a name, so "elements ::= cp" is no good.

   484 </sitem>

   485 <sitem>1996-11-11 : CMSMcQ : revise for style.

   486 Add new rhs to entity declaration, for parameter entities.</sitem>

   487 <sitem>1996-11-10 : CMSMcQ : revise for style.

   488 Fix / complete section on names, characters.

   489 Add sections on parameter entities, conditional sections.

   490 Still to do:  Add compatibility note on deterministic content models.

   491 Finish stylistic revision.</sitem>

   492 <sitem>1996-10-31 : TB : Add Entity Handling section</sitem>

   493 <sitem>1996-10-30 : TB : Clean up term &amp; termdef.  Slip in

   494 ERB decision re EMPTY.</sitem>

   495 <sitem>1996-10-28 : TB : Change DTD.  Implement some of Michael's

   496 suggestions.  Change comments back to //.  Introduce language for

   497 XML namespace reservation.  Add section on white-space handling.

   498 Lots more cleanup.</sitem>

   499 <sitem>1996-10-24 : CMSMcQ : quick tweaks, implement some ERB

   500 decisions.  Characters are not integers.  Comments are /* */ not //.

   501 Add bibliographic refs to 10646, HyTime, Unicode.

   502 Rename old Cdata as MsData since it's <emph>only</emph> seen

   503 in marked sections.  Call them attribute-value pairs not

   504 name-value pairs, except once.  Internal subset is optional, needs

   505 '?'.  Implied attributes should be signaled to the app, not

   506 have values supplied by processor.</sitem>

   507 <sitem>1996-10-16 : TB : track down &amp; excise all DSD references;

   508 introduce some EBNF for entity declarations.</sitem>

   509 <sitem>1996-10-?? : TB : consistency check, fix up scraps so

   510 they all parse, get formatter working, correct a few productions.</sitem>

   511 <sitem>1996-10-10/11 : CMSMcQ : various maintenance, stylistic, and

   512 organizational changes:

   513 Replace a few literals with xmlpio and

   514 pic entities, to make them consistent and ensure we can change pic

   515 reliably when the ERB votes.

   516 Drop paragraph on recognizers from notation section.

   517 Add match, exact match to terminology.

   518 Move old 2.2 XML Processors and Apps into intro.

   519 Mention comments, PIs, and marked sections in discussion of

   520 delimiter escaping.

   521 Streamline discussion of doctype decl syntax.

   522 Drop old section of 'PI syntax' for doctype decl, and add

   523 section on partial-DTD summary PIs to end of Logical Structures

   524 section.

   525 Revise DSD syntax section to use Tim's subset-in-a-PI

   526 mechanism.</sitem>

   527 <sitem>1996-10-10 : TB : eliminate name recognizers (and more?)</sitem>

   528 <sitem>1996-10-09 : CMSMcQ : revise for style, consistency through 2.3

   529 (Characters)</sitem>

   530 <sitem>1996-10-09 : CMSMcQ : re-unite everything for convenience,

   531 at least temporarily, and revise quickly</sitem>

   532 <sitem>1996-10-08 : TB : first major homogenization pass</sitem>

   533 <sitem>1996-10-08 : TB : turn "current" attribute on div type into 

   534 CDATA</sitem>

   535 <sitem>1996-10-02 : TB : remould into skeleton + entities</sitem>

   536 <sitem>1996-09-30 : CMSMcQ : add a few more sections prior to exchange

   537                             with Tim.</sitem>

   538 <sitem>1996-09-20 : CMSMcQ : finish transcribing notes.</sitem>

   539 <sitem>1996-09-19 : CMSMcQ : begin transcribing notes for draft.</sitem>

   540 <sitem>1996-09-13 : CMSMcQ : made outline from notes of 09-06,

   541 do some housekeeping</sitem>
