Hi Mukul,
I'm afraid I don't follow how that could work. I see nothing in the code
which sets the default function namespace [1] to be
"http://www.w3.org/2005/xpath-functions";. XML Schema 1.1 [2] fixes its
value to be "http://www.w3.org/2005/xpath-functions";, but an XPath 2.0
processor should allow you to set it to anything, so can't see how it could
be working correctly without having code somewhere in Xerces which
explicitly sets that on PsychoPath.
In other words a call like:
fDynamicContext.set_default_function_namespace
("http://www.w3.org/2005/xpath-functions";);
or whatever the method is in PsychoPath for specifying it..
Thanks.
