I think it was previously discussed in html-ig under various topics,
the last being New Highlighting.html -- I hadn't discovered that mailing
list until Dan forwarded my msg there. You were discussing the merits
of "< S >" versus "< STRIKE >", and a proposal to add "< NEW >" to
indicate new text.

By the way, in WordPerfect(R) the terms are "STRIKEOUT" and "REDLINE".
I don't particularly like these, though, because they seem to be
dealing mainly with the display mode. Someone commented earlier that
"STRIKE" has connotations of overstriking the letters. I'd rather see
names that dealt more with structure, like "DELETED" and "ADDED".

I am not a lawyer but a programmer, and I want the feature for
displaying modifications to code listings. If the < insert > tag
were available as well as the < strike > tag, browsers could be made able
to display the old version, the new version, or a combined version "marked up"
to highlight the changes.

I'd want the browser to be able to do this under user control.
For example, X-MOSAIC could have some X-resources and menu items controlling
the display modes.

For example, to display the old version:

StrikeTextColor: black
StrikeTextDisplay: true
InsertTextDisplay: false

or pick a menu item, "strike-insert display mode/old"

and to display the "marked up" version

StrikeTextColor: light grey
InsertTextColor: cinnamon
StrikeTextDisplay: true
InsertTextDisplay: true

or pick a menu item, "strike-insert display mode/markup"

I can imagine software that would compare two files and create an
HTML document containing the appropriate STRIKE or INSERT (or whatever they
might be called) tags.

I can also imagine some implementation nightmares for browser
developers, e.g. how should anchors and images be displayed inside a STRIKE
or INSERT pair?

But I suppose the lawyers might like this, too. And mathematicians
and artists might appreciate the symmetry that's lacking if you only have
< strike >.

If this is the wrong place to post suggestions for improvements to
HTML, forgive me, and tell me the right place.
