There's a difference between document-uri and base-uri. document-uri is a URI
that can be used to fetch the document using the doc() function. base-uri is a
URI that can be used to resolve relative URIs contained in the document. You
talk about document-uri, but I think you mean base-uri.

As David points out, you can control the base URI of the constructed document
using an xml:base attribute in the stylesheet.

You can't set a document URI (it's a temporary tree with no means of external
identification. That means that the garbage collector knows when it can kill
it. This wouldn't be the case if it had a document URI. If you want to create
a document with a document URI, use xsl:result-document - except you can't
then access it during the same transformation.)
