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
