Subject AW: [C2.0b2] Bug in XIncludeTransformer
Date Tue, 24 Jul 2001 13:26:09 GMT
I don't know the real problem for this, but the XIncludeTransformer
does not implement the recycle() method to reset the stack for
a new processing round.

If someone has the time to fix this, I would be very glad. (Resetting
the stack and setting all other instance variables to null).
