Glad to hear someone else is interested!

I have a couple of questions about your XLink/styling experience.

[Didier's original descriptions are at
http://lists.w3.org/Archives/Public/www-style/1999Apr/0002.html.  They're
pretty long and quite detailed!]

Were your experiments with XSL or CSS?  I seem to think they were XSL, but
I'd still be very glad to work on CSS with the problems you've encountered
in mind.

Did you actually deal with inclusion of non-XML materials, like graphics?
Or was it all XML documents/fragments?

Finally, does the W3C's fragment working group have anything going that
might address the problems you encountered with fragments?

This is where it's going to get ugly.  I suspect the Link folks will point
to the style folks and vice-versa, which is why I'd like to get the world
talking about this early.

I'm still not convinced that style sheets is the best place to handle this,
but it seems to be the dumping ground for anything involving presentation
and/or behavior.  Since XML doesn't have the rules HTML provided, we'll
have to do something.

Hmmm... maybe I should get out the latex makeup and paint my face green...
