Please take the time to carefully read and comment on section 4.4 (Functions) in the draft XPath 4.0 spec

There's quite a lot of complexity here and I suspect a thorough review will take more than one meeting.

There's certainly something to be said for agreeing foundational material like this before we consider the design of specific functions that can take advantage of it. On the other hand, there's also a bit of a risk of getting bogged down...
