follow-up: document function issue - relative URIs

what is actually the difference between "the source document" and the "stylesheet"? 

should an xslt processor (also 1.0 processors like Xalan or Saxon 6.x) resolve the URI parameter of a document function call - e.g. document('somedir/somefile.xml') - normally relative to the stylesheet in which the call is in? 

i ask because i noted that e.g. Pyana (Python wrapper for Xalan-C) does seem to resolve a document call relative to the Python module that actually does the transformation, or more precisely relative to the main program module (which may import the transformation module).
some other server products (e.g an ATG-Server) seem to handle it different again.

is there any reliable or better said theoretically correct way of interpreting a relative URI? with theoretically correct i mean how it should be for most processors/configurations or even better as stated said in the xslt specification (does it say anything about it?).


hope my question makes sense...
thanks
chris
