Yes.

Sort of, but not really how you're thinking.

XML "doesn't do" includes. There are various techniques applicable, but
they're either not workable, not implemented, or just not commonly
used. It's also relatively rare to use the <?xml-stylesheet ... ?> PI.
 Most XSLT gets transformed on servers (for widespread output device
compatibility) rather than getting shipped out as XML with a linked
stylesheet and transformed on the final device.

So the linkage of content and presentation stylesheet is (in general)
done by external non-XSLT scripts calling XSLT engines from outside. If
you want to describe this linkage in an XML format then of course you
can do so, but most ways of doing it are project-specific and don't use
a clearly defined or standardisaed format.  You can of course use the
PI attached to the document and read this from your script, then use
that to indicate the XSLT transform to use.

You might also find a look at the XInclude protocol and the Cocoon
project to be useful.
