David,

Whereas currently it's raises an error, of course - nothing to do with
the fact that strings aren't split into characters, but rather because
predicates can only be used on steps, and general steps must return
node sequences.

So:

  (1, 2, 3)[2]

is an error according to the XPath 2.0 WD, as far as I can tell.

Which strikes me as rather peculiar, personally.

Cheers,

Jeni
