4. Extend the formula langauge with a "cases" construct.

7. Fix translation of slides into TeX.  Tables and other figures
should not float.  This requires context sensitive translation and
will have to wait for James Clark's replacement for sgmlsasp. (As of
1.3, there is an attribute for keeping these from floating.)

11. Add an index to the manual

21. Extend the DTD and the LaTeX mapping to support the automatic
generation of indexes.  Talk to Hans-Werner about this.

22. Extend biblio DTD to allow cross references <em/within/ the
bibliography.  For example, the item for an article in a collection
could refer the item for the collection, rather than provide all of
the information about the collection again.    BibTeX can handle this,
but it requires an extra latex pass.   Request from Joachim.

24. format -T max ...  needs a postprocessor to remove empty
paragraphs.  This problem is a side-effect of the short
references used for opening and splitting pargraphs.  Perhaps there is
a better way to use short references which does not suffer from this
problem.  We may also want to consider going back to require an 
explicit <p> starting tag, at the risk of breaking some documents.

25. The roff mapping for <ar> elements is buggy.   Tables may not
be included within EQN formulas.

26. The roff mapping for <fi> elements should be changed.  Font
requests are not allowed within equations by EQN.

27. Need some way to have successive cites be formatted properly by
LaTeX. Refer does the right thing.  I thought we might just be able to
change the <cite> and <ncite> elements to allow cdata content, instead
of empty content, but this is not upwardsly compatible.  When content
is empty the end tag may be ommitted. Once content is permitted,
text after existing cites gets interpreted as being part of the
citation if the end tag was ommitted.   Try something like this:

<!element cite - - "CDATA, (cand, CDATA)*" >
<!element cand o o empty>

This CDATA might need to be RCDATA, to allow entities for non-breaking
spaces in "pg.&nbsp;23", for example.

28. German quotation marks, when german style option is selected.

29. "Motto" element, for quotations at the beginning of a chapter or
section.   

30. Change the SGML declaration so that is uses the Latin 1 character
set.  Write sed scripts for converting between Latin 1 and Macintosh
character sets.  This has several advantages over using entities:
1) Much easier to type German using Author/Editor, at least until it
supports keyboard macros.  2) Search and replace of non-ASCII
characters works in Author/Editor, where entities cannot be included
within search or replacment strings.  3) Only need one replacement
file for the Latin 1 entities.  TeX 3.0 and groff both support Latin
1.  Disadvantage: Macinthosh Author/Editor files which use non-ASCII
characters will need to be translated into Latin 1 to satisfy the DTD.
(Leave the entities for Latin 1 characters in the DTD, for upwards
compatability and to support 7 bit ASCII.)

31. Consider reducing the set of mappings, to ease maintenance.

32. Remove short references maps from the DTDs to the extent they are
dependent on a particular processor or formatter, such as TeX.
Instead, include formatter dependent short reference maps using the
same technique now used for entity translations.  This would also
solve the problem of having to comment out short reference maps for
use with Author/Editor, which doesn't support them.

33. Add entities for large math operators. (e.g. bigcup)
