Question on adding Xpath2.0 functions to Xalan2.6?

[Andrew Fielden <af...@tibco.com>]

I'm using a stylesheet that was created for a custom xslt engine which 
makes use of Xpath2.0 features, specifically the exists() function. 

We're now using the stylesheet with Xalan 2.6, which does not support
Xpath2.0. 

So I need to write a custom exists() function and register it 
programatically in Java with Xalan. 

I've consulted the Apache website, and the examples typically involve 
creating extension functions in a custom namespace, then modifying the 
stylesheet to use these functions. In my case I am not able to modify 
the stylesheet. 

My question is can anyone give advice on how I provide and register an 
implementation of  exists() with the Xalan engine so it can process my 
stylesheet? 

Any examples would be very useful. 

Thanks for any help. 
Andrew.
