RE: [xsl] What is wrong with this key element?

Either index the attributes, using

<xsl:key name="prodCat" match="@ProdCode" use="substring(.,1,3)"/>

or index their containing elements, using

<xsl:key name="prodCat" match="z" use="substring(@ProdCode,1,3)"/>

The use expression is evaluated with the matched node as context node; with
@ProdCode as the context node the expression @ProdCode gives you nothing.

I prefer to index the element nodes rather than their attribute nodes, but
both should work perfectly well.
