If we really get to the point where there are significant user bases
with access to only one of the alternatives, we would have to hope that
it's possible to translate CSS into DSSSL.  But is it really likely that any
of the major US vendors will support DSSSL and not support CSS?

A possible model is that serious authors (those with ""heavy" stylesheet
needs) would specify both DSSSL and CSS stylesheets and provide
documents via servers that recognize DSSSL-capable UAs and serve the
right STYLE element for the delivery vehicle.

That's a question I wondered about, too.  Why not just create a
DTD for stylesheets, like

		WEIGHT (important|legal|normal)

giving (for bits of the HTML 2.0 sample in the CSS1 spec):

		<RULE elements=BODY>
			<PROPERTY> margin=1em
			<PROPERTY> font-family=serif
		<RULE elements="H1,H2,H3,H4">
		<RULE elements="IMG" context="A:link">
			<PROPERTY> border-color=red

Or even create separate elements under RULE for each property, as in
your example.

I don't know the answer.  Naming and character restrictions might have
been an issue. The extra bulk of the SGML notation might have been an
issue.  Maybe the authors would like to comment.
