Yes, that's how it works. I didn't explain it deliberately - people
shouldn't use code fragments without doing the work to understand them.

I often write select="(pages, 0)[1]"
Clarification please,
generate a sequence which has either one or two items;
then take the first?
Sequence is either
[123, 0]
or
[0]
which gives what the OP wanted?
Is that right (DC terminological corrections notwithstanding).
TIA, DaveP.
