In Saxon, //bar is handled by an index, so exists(//bar) should be quite
fast after the first time (when the index is built).

Subject: [xsl] Cost of complex match patterns
Out of interest, given the match patterns:
match="foo[//bar]"
match="foo"
Should the former be avoided, or because it's within a match
pattern it's converted to a simple lookup so it's fine?
(I realise this is implementation dependent, just curious)
