[xml] XPath functions ignoring their name

[Thomas Broyer <tbroyer ltgt net>]

Hi,

As I explained in the xslt list, I need a way of retrieving the name of the
currently called XPath function since I have a single function answering
calls for multiple XPath functions (this is for the EXSLT - Functions
implementation).

It seems impossible: the parser context doesn't keep track of the current
xmlXPathStepOp

Can I add a pointer to the current xmlXPathSetOp, or its index in the
comp->steps list, or directly to the function name and namespace URI (which
of the three should I prefer?), in the xmlXPathParserContext?

Tom.
