Michael, doesn't the count() function require access to the whole subtree?
How would a count be conducted by sitting at the top of a subtree? Perhaps
you meant to say that the count() function is an absorption operation?
I wondered this too... I'm guessing you could do a look-ahead of the
xml parsing the structure without any text nodes, then you have the
'metadata' without the content. Will be interesting to find out...
