Re: [xsl] Keys off of variable xml source

---

---

The reason for a lookup xml source is to act as a cross-reference to
data in the main xml source.  So, I need to reference all elements
who's ID = 123 but my match is expressed as a code value "abc".  The
code "abc" maps to 123 in my lookup.
So, I'm still scratching my head wondering how I might effectively put
the external file to use with keys, but thinking it won't work, the
context would strictly be of the main xml source.
