<!-- Rainbow DTD: CHANGE LOG

   version 2.5 by alb:
        *) 1994/12/28 proforma attribute on CLF, permitting clf with no overrid
es
        *) 1994/12/23 SYSATTR on TABLE, ROW, and ENTRY
        *) 1994/11/29 ANCHOR may be a sibling of PARA (for RTF)
        *) 1994/11/21 XREF may contain TABs
        *) 1994/11/03 arch-type, arch-type-info added
   1994/06/02 (RCS version 2.4) by alb:
        *) NAMEDCLFs nested, continue attribute
        *) NDATA NOTATIONS & entities for graphics and equations
           Notation names are 3 letters in length to facilitate their
           acting as DOS filename suffixes.  (That means our notation names
           are not compatible with those recommended by ISO/IEC/JTC1/WG8)
        *) Fix for AUTOGEN content model: can contain TAB

   1994/05/10 (RCS version 2.3) by dfs:
        *) Major new release.  For full details, see the "Annotated DTD"
           document, available in PostScript form via the FTP server.
        *) DTD is now auto-generated from the WinWord "Annotated DTD" document.
           This allows dfs to maintain the DTD by editing a single
           document, instead of doing error-prone multiple-file editing.
           The side-effect: the rainbow.dtd file is not as pretty as it once
           was, for vertical spacing is not provided.
        
   1994/02/21 (RCS version 2.2) by dfs:
        *) HEAD is now merely a wrapper around one or more PARAs.
        *) STRUCLVL now supports the ID attribute.
        *) SGML declaration now fully supports ISO 8859-1 character set, and
           is stored in a separate file (rainbow.dcl) for convenience.
        *) CLFTYPE now supported; NAMEDCLF elements can be used to refer to
           a CLFTYPE.
        *) NAMEDCLFs can contain CLFs, thus providing limited nesting of
           character-level-formatting objects.
        *) Definition of an SDATA entity for representation of tabchars.
        *) ANCHOR, IDXTERM, and XREF: content model repaired to match the
           original intended semantics.  The content models are now
           repeatable OR groups.
             NOTE: This leaves AUTOGEN and CLF as the only element types
                   with controversial "mixed content" models.  We hope
                   to resolve these controversies at the SGML/Open
                   Rainbow review.

   1994/01/24 (RCS version 2.1) by dfs:
        *) Set SHORTTAG to YES in SGML decl (recommended use: only to
           allow omission of attribute-value delimiters)
        *) Various additions to the set of element types supporting
           end-tag omission.
        *) This change log was moved out of the SGML decl.
        
   1994/01/10 (RCS version 2.0) by dfs:
        ** Very large number of changes - -  see the Annotated DTD document
           for complete details. **

   1993/12/06 (RCS version 1.9) by dfs:
        *) The SGML declaration minimization portion now allows OMITTAG.

   1993/12/06 (RCS version 1.8) by dfs:
        *) Font size is no longer a NUMBER (to support fractionals)

   1993/12/05 (RCS version 1.7) by dfs:
        *) Deletion of "continue" attribute on PARA/HEAD.  That attribute
           never really existed; it was a mega-typo.
        *) Addition of "dtdver" attribute allowing a document instance
           to specify the exact version of Rainbow DTD used by its
           generator/author.
        *) Addition of copyright notice to DTD.

   1993/11/30 (RCS version 1.6) by dfs:
        *) MARK now has same content model as PARACONT.

   1993/11/29 (RCS version 1.5) by dfs:
        *) Typo fix: TXTFLD changed to TEXTFLD

   1993/11/29 (RCS version 1.4) by dfs:
        *) All PLF/CLF attributes are #IMPLIED.
        *) NUMBER type now used very sparingly, because of its inability
           to support negative numbers.  NUMBER now used only in cases for
           which a negative number is absolutely impossible.
        *) All ID attributes are of type CDATA, because word processors
           allow "bookmarks" to have names that do not meet the SGML
           requirements for ID-type attribute values.
        *) GI change: INDEXENTRY is now IDXTERM
           Motivation: it was the only GI that was > 8 chars in length
        *) IDXTERM was an "orphan" in the previous version; now it is
           included in the DOC content model as an inclusion exception.
        *) The PARACONT attributes are now #IMPLIED.
