RE: [xsl] Inconsistent interpretation of // relative to document()

["Michael Kay" <mike@xxxxxxxxxxxx>]

As others have said, the difference is probably that the stylesheet has a
different base URI in the two cases. The base URI is an implicit argument to
the document() function. When using JAXP, the base URI is set when you call
setSystemId() on the Source object used to construct the Templates object.
When using Ant, I'm afraid I have no idea where the base URI comes from -
but you can avoid problems by supplying an absolute URI as the value of the
parameter, or by calling resolve-uri() to control the URI resolution
yourself.
