Yup, define a key like:

<xsl:key name="foo-key" match="foo"
         use="concat(@name,' ',@version)" />

Then further on use:

<xsl:variable select="//foo[generate-id()=generate-id(
                key('foo-key',concat(@name,' ',@version)))]" />

To give you the nodeset containing all foo nodes whose id equals the first
node returned by key().


Apply templates to the variable, and you're set.
