! Your XSL incorrectly reassigns the variable foo which breaks the
! functional programming model outlined in M Kay's XSLT book. I too
! ran into the same problem when converting from 2.1 -> 2.2. The thread
! should be in an archive. Xalan 2.2 still allows variable reassigment
! which is invalid, the problem you are having is that it treats the
! second variable foo as a new variable, so you can't assign a variable to
! itself because it has not been created yet.
! 
! Read chapter 8 of Michael Kay's book on functional programming, there are
! a few good examples on how this operation can be coded correctly in XSLT.
! Be carefull because it requires a new way of thinking on how to use variables.
! Thought of the day, side effect free programming...
