Interesting idea. It would have to be in some kind of diagnostic mode (a) because of the performance implications, and (b) because overriding templates is good and normal practice and you don't want to produce large numbers of warnings about something that's perfectly respectable. I actually find that "overriding" bugs are one of my most common errors in Java that the compiler doesn't catch. It's infuriating that when you misspell a method name in a subclass, or get the arguments wrong, the method is just silently ignored. So I can see that in complex XSLT applications, there might be similar effects. Michael Kay http://www.saxonica.com/
