Thanks David and Jeni for the hint.
Actually, that doesn't matter in XSLT 1.0, since if you supply a
node-set to the generate-id() function it gives you the generated ID
for the first node in that node-set automatically. But I usually put
in the [1] anyway (a) because it makes it clearer what's going on and
(b) because in XSLT 2.0, it's an error to supply more than one node as
the argument to generate-id().
Now I know why I get confused sometimes. The operators _do_ work on nodesets,
but functions _don't_..
This has nothing to do with operators/functions -- just the way XPath
1.0 and XPath 2.0 react to a sequence of more than one item when just
one is expected.
Of course, the picture is a little bit more complicated, because we
have backwards compatibility (version="1" in scope) and calculating
the EBV (Effective Boolean Values), that cause XPath 2.0 to behave
(almost) as XPath 1.0.
Or did I get it wrong? :o)
Cheers,
Dimitre.
