I think there is some kind of misunderstanding here. What you are 
describing is, in my opinion, closer to what the following would do for 
XPath on an XML tree:
  <xsl:apply-templates select="//*" />

What I was considering was an equivalent of:
  <xsl:apply-templates select="*" />

which only selects children of the context node and thus limits the 
scope of application of the XSLT instruction.

The question is, can we even conceptually define an equivalent of this 
for a general directed graph?
