[Bug 16744] [FO30] fn:collection-available

One possible reason is that if collection-available() has parallel semantics
with the other functions, it could be quite expensive: it has to determine not
only that a collection with the required name exists, but that it can be read
in its entirety without error. Given that many operations on collections are
likely to filter the collection, which might mean that some errors go
undetected, the operation could be expensive. But I agree that's not a strong
justification.

There is however a process argument against adding it now: the time for adding
new features to the current 3.0 version of the spec is past.
