Nope, I was suggesting that the css could be used by the xslt's result
tree (if that had a <link rel...> ) if that was the developer's purpose,
since I don't really see any reason of having two PIs pointing at a css
and an xslt at the same document, unless there is some kind of mechanism
for choosing the appropriate one.

Although that sequence is not really logical or useful (in my tired mind
at least) I do get your point. This may well be a simple but effective

Sorry for not being clear. I just thought that since W3C has gone
through all this work of building specifications such as css media
queries and DOM, how come I cannot write something like:

?xml-stylesheet href="a.xslt" navigator="IE" ?>
?xml-stylesheet href="b.xslt" navigator="DOM2" ?>
?xml-stylesheet href="c.xslt" navigator="text" ?>

OR whatever, meaning that we should had ways of quering about agent
capabilities already, in more detail than (the generalised as a consept)
css media queries allow.

Kindest regards,
