I don't know of anything built into Xalan for the purpose, though it's 
certainly an interesting suggestion.

I doubt it.

I'm assuming you have a set of classes that provide all the secure 
information, however. If a user altered the style sheet, added their own
extension functions, don't they still have to add some point then call 
your 
classes to get the secure information, and therefore, isn't that the point 

were you
can enforce security. Perhaps, i'm still not grasping the entirety of your 

problem.
