Hi Tim,

I have uploaded the latest copy of my DTD for HTML+ into
[tbl moved it into:]

    "ftp://info.cern.ch/pub/www/dev/htmlplus.dtd"


The new DTD reflects recent discussions:

    o   One tag for all inline emphasis
    o   FIG tag similar to Pei's (but no TYPE attribute)
    o   EMBED tag for foreign data (simple equations etc.)
    o   DL lists extended for tables with optional hints
    o   INPUT and SELECT form interaction elements

I don't know how in SGML to specify a tag which may or may not
have an endtag depending on its attribute values. Because of
this I have used two tags for images:

[I think (hope?) that this it is impossible to change
 the EMPTY charactistic of an element as a function of the
 attributes.  Would severly complicate parsing -Tim]
 

    a)  <FIG> ...</FIG> for captioned images
    b)  <ICON> for small inline graphics without captions

[...]

Cheers,

Dave Raggett
