Provided that the primary input document has a URI, it should be possible to
obtain it using either document-uri() or base-uri(). 

In the case of Saxon, I think that if you use a user-written URIResolver it
is possible for these to be different (document-uri() is the URI given as
input to the URIResolver, base-uri() is the SystemID property of the Source
object returned by the URIResolver), but in most cases they will give you
the same answer.

It is possible to supply a primary input document with no URI, for example
in the form of a DOMSource or a StreamSource whose SystemID property has not
been set - but it's not recommended and is a common source of trouble.
