Yes, sorry, I meant that if the document() function were not already
defined, you could imagine that one way in which it could be defined
would be such that:

  document('foo.xml') == document('foo.xml')

were false. It isn't designed like that, for the good reasons that
we've discussed on this thread, but it would have been a feasible
decision. I was comparing that to the current() function, where it
would never make sense for current() == current() to be false.

Cheers,

Jeni
