[XQZone General] limiting server output

[Howard Katz]

Hi Darin,

Thanks, I have considered that option (tho I'd probably write it as $result[
position() = 1 to 500 ] to be consistent with the latest state of the
specification). That doesn't answer the scenario tho, in which one or more
of the $result nodes themselves root(s) one or more large trees, and so on
downward. I've been mulling whether there's some reasonably straightforward
way of iterating through $result and its subnodes on my own, counting as I
went, but I haven't thought it through in any detail at this point.

Howard
