I am looking for some help in doing grouping in XSL.  I can group once (tha=
nks to the FAQ at dpawson), but I need
to group again, based on the same tree.  Here is sample data:

<Transactions>
	<Transaction id=3D"1">

<Transactions>

This is one transaction.  First we group by Status, no prob.  Now I want to=
 group by CurrencyCode within each
Status group.  I'm just not seeming to get the right combo of xsl:key and k=
ey() XPath in the sub for-each.  Can
someone lend a hand?  Tx :)
