multiple stylesheet for an XML file

when an XML file is accessed in the internet, the usal way to associate
a stylesheet is the <?xsl-stylesheet ...?> tag.

But what if I want to assiociate more than one stylesheet to the XML
file, depending of the URL. Copying the XML file and changing the link
to the stylesheet is not a satisfying solution...

Isn't it possible to have "fake" XML file with just the <?xsl-stylesheet
...?> tag and a link to the XML data file ?

Or to assiociate the stylesheet dynamicly with an arg passed througth
the URL ?
