Well in that case ... you're sure to have figured out that having to 
use the same monster path twice -- once in an xsl:if for the "wrapper 
logic" and a second time inside the "if" clause to select the nodes 
themselves -- makes for all the more reason to bind it to a variable. 
It will prevent a processor that has no optimization for this from 
looking through the entire document repeatedly for the same nodes.

As for being excited by this: I guess that's what makes you a 
computer programmer.
