Well, for that particular expression I think "except" works just fine.
It was when the right hand side referenced current() that I thought it
didn't work. I think the intent of the "until" was to be able to cite a
singleton on the right hand side.
Hm, funny. I inferred from Mike's suggestion that any arbitrary
expression, returning a Boolean, would be allowed on the right hand
side, evaluated with the item in the sequence as context.
//* until (. is current())
or
if (exists($seq[expr])) then
$seq[position() le index-of($seq,$seq[expr)]
else $seq
where expr is an arbitrary expression returning a Boolean.
Cheers, Wendell
