xsi:type typing support

This code illustrates some of the pitfalls:

(a) if you're using xsi:type at all, then surely you should be treating it
as a QName, in which case you can't compare it to a string.

(b) relying on xsi:type gives you no way to associate a type with attributes
rather than elements.
