Re: [xsl] Grouping with keys

Silvia L.,
I was messing around with this and came up with a solution.

I probably write things different than you do. Others on this list
would greatly simplify these templates. However, I wanted you to see
how it works. I use for-each only in special circumstances.

Hope you like it.
