No, it's not a separation of form and content issue, it's a processing
model issue.  My suggestion was aimed squarely at support for form
control (like inclusion of boilerplate headings for certain classes of
paragraphs or control of the order and punctuation of elements within
compound elements (admittedly, with the HTML DTD this would require
ugliness, like using a classed SPAN to define the compound element, but
the capability would make the stylesheet model suitable for use with
extended DTDs that *do* have meaningful compound elements, too)).  The
transformations important to me are purely form, not content.

Actually, now that I think about it, I guess I could work around the
restriction, by allowing the right hand side of the rules to specify
multiple spans, with independent typographic styling:

	P.abstract	{ "Abstract" font-weight: bold, #value }

where top-level commas separate sequential output forms.  This would be
a little bit of a hassle for the author, who would have to be careful to
coordinate the styled spans with the built-in markup (so that the
styling of Abstract, in the above example, matched the styling of a
<B> element in the text), but I guess it would be workable.

So, given a restriction on including markup in the right-hand sides,
what does the group think about the proposed text-manipulation
capability?
