It's always possible they simply forgot to extend it when key was 
extended in xpath.

It's not a restriction on functionality just a restriction on syntax 
since if

 <xsl:template match="key('maindoc','Sal',$doc2)">

were allowed it would presumably be the same as

 <xsl:template match="key('maindoc','Sal')[ancestor-or-self::node()[. 
is $doc2]]">
