You will need to show the relevant XML and explain which nodes you are 
interested in, then we can hopefully sort it out.

xsk:key is a top level element but you can certainly specify a match 
pattern for nodes at any level. For instance
   <xsl:key name="k1" match="foo[your predicate here]" match="."/>
is certainly possible to define the key only for 'foo' elements 
fulfilling your predicate.
