Thanks Joe.  Here's an example below, if an item of set 2 is found in
set 1 then remove if from set 1.

I'm relatively new to xsl and see there's a key function and maybe
that could be used do determine which nodes to copy.

The source could be a relational store but was trying to be safe and
build this agnostic to source.
