Yes, provided the data is held in a file or other URL-addressable
resource - see http://www.w3.org/TR/xslt.html#function-document. You can
may also be able to pass XML documents in as global parameters - see the
attached jscript for a demo of this using msxml4. (Feature should work
using msxml3 too.) 

This makes a more attractive prospect if you're working with large
in-memory documents in a heavily stressed server environment and you
don't want the load of serialising, saving, re-loading and re-parsing
the documents in question - it also allows you to import the results of
HTTP POST or SOAP based web services efficiently.
