If main.xml, main.xsl and users.xml (referenced in the stylesheet)
are really in the same directory, then it sounds like a bug (on
url resolution). It is XSLT problem (document() function is one
from XSLT spec). In such case please file it to bugzilla and I'll
fix it later.

For workaround you can pass the full path filename as a variable
(for document() argument) in XsltArgumentList argument for
XslTransform.Transform().
