In XSLT/XPath 1.0 one would use:
not($node-set)
to find if $node-set is the empty node-set.
However, the same test on a sequence in XPath 2.0:
not($seq)
may return 'true' for a non-empty sequence -- e.g. for:
( false() )
or for
(0)
My question: Is there a more efficient test for an empty sequence than
count($seq) = 0
