Changes from DocBook V2.4.1 to DocBook V3.0:

Markup:

- Added optional Dedication element after BookInfo.

- Added optional Sect<n>Info elements at the beginnings of Sect<n>
  and optional RefSect<n>Info and RefSynopsisDivInfo elements at the
  beginnings of their respective container elements.  These all contain
  a free mixture of metadata-related elements.  Where IndexTerm was
  excluded before, this exclusion was removed, since IndexTerm can now
  legitimately appear inside the new IndexTermSet.

- Added several CALS-based presentational attributes to Graphic and
  InlineGraphic.

- Added an "SGML" notation.

- Broadened the content of BiblioEntry, DocInfo, BookInfo, and SetInfo
  (allowing a mixture of any of the bibliographic identifiers and, a new
  addition, the person.ident.mix elements), changed the way BiblioMisc
  is to be used, added an intermediate BiblioSet container element, and
  added the BiblioMixed and BiblioMSet elements for "cooked" entries.
  Added Relation attribute to BiblioSet and BiblioMSet.

- Removed #PCDATA from SetInfo in the process of updating it to the
  new bibliographic model (bug fix; backwards-incompatible).

  and added them to the bibliographic information elements.

  GlossDiv, RefEntry, RefSect<n>, and Article.

- Added Label attribute back to Footnote (bug fix).

- Made FootnoteRef EMPTY and changed its Mark attribute to Label
  (backwards-incompatible; previously announced).

- Added Pagenum attribute to ToC.

- Added Acronym to word.char.mix and the content of SystemItem, 
  and excluded it from itself (because Acronym contains word.char.mix).

- Changed Revision* to Revision+ in RevHistory (backwards-incompatible;
  previously announced).

- Renamed SpanEnd attribute on IndexTerm to StartRef
  (backwards-incompatible; previously announced).  Added Class attribute.

- Added Conformance effectivity attribute.

- Added Alt element to Equation, InformalEquation, and InlineEquation.

- Added NumCharRef token to Class attribute of SGMLtag.

- Broadened the Article content model and added a Class attribute.

- Added Emphasis to the content model of Superscript and Subscript
  (bug fix; accidentally removed in V2.4).

Other:

- Defined most of the *Info elements in one fell swoop using a new
  otherinfo.class parameter entity.

- Moved entities that define xxx.module and xxx.content.module 
  marked-section status keywords to be near the actual marked sections.

- Removed citerefentry.content.module because its subelements weren't
  unique only to CiteRefEntry.

- Moved some ELEMENT/ATTLIST declaration pairs out of the "words"
  section and into the "computer terms" section.

- Added FUTURE USE comments explaining what backwards-incompatible 
  changes are planned for V4.0.

- Added parameterization that allows individual elements' Role attributes
  to be easily customized or removed.

- Added reference to local.shortcut.attrib entity in Shortcut (bug fix;
  it was missing).

- Changed over to the SGML Open full CALS table module.  This should not
  result in any markup model changes.

- Alphabetized the contents of the word.char.class entity.

- Updated Terry Allen's contact info and copyright statement in comments
  in the files.

- Added bibliocomponent.mix entity to help manage bibliographic
  information and reorganized the title/bibliographic section into
  three sections: titles, bibliographic, and subject set etc.

- Changed the FPI keyword for dbgenent.mod to ENTITIES from ELEMENTS
  (bug fix).

- Made an entity for the semi-common Width attribute and referenced
  the entity from the objects that have Width.

- Added a version number to the dbgenent.mod module, its FPI in the
  catalog, and its FPI reference in docbook.dtd.

- Changed the names of some parameter entities: from
  [local.]cptr.char.class to [local.]tech.char.class, and from
  [local.]word.char.class to [local.]gen.char.class.

- Removed the SGMLDECL entry from the docbook.cat file because the
  DocBook SGML declaration may not be appropriate for other SGML
  applications.

- General coding and comment cleanup.

Following are the changes made to DocBook V2.4 to create V2.4.1:

Version update
==============
o In all modules, the version number has been updated in the header
  comments, FPI instructions, DTD module entity declarations, and
  catalog entries.  (Note that dbgenent.mod does not mention a version
  number since it is expected to be edited by users.)

Substantive changes (bug fixes)
===============================
o In docbook.dtd, three notation declarations (EQN, PIC, and TBL) have
  been changed to have null system IDs because the original identifiers
  were formed as approximate public IDs, not system IDs (and because
  they contained an ampersand, they were not valid FPIs either).  We are
  investigating whether there are proper formal public IDs for these
  notations.

o In dbpool.mod:

  - The %vendor.attrib; entity containing the Vendor effectivity
    attribute (new in V2.4) has been added to %effectivity.attrib; in
    order to make the attribute available for use.

  - The MenuChoice element (new in V2.4) has been added to
    %cptr.char.class; in order to make the element available for use.

  - The content model of Shortcut (used inside MenuChoice) was changed
    to match that of the new KeyCombo element, as its original design
    intended.

  - The Option element was added to the content model of Group in
    CmdSynopsis to bring the model up to what the documentation
    (correctly) describes.

Editorial changes
=================
o The copyright statement has been updated to help ensure continued free
  access to DocBook files by users.

o Spelling in comments was fixed, and comments explaining some attributes
  were clarified.
