Log Message:
-----------
Fix bug in original implementation of xmlserialize(): if user specifies
a target type that isn't acceptable, the code failed to raise the proper
error. The result instead was to return a NULL expression tree, which
in a quick test led to a 'cache lookup failed for type 0' error later.
Patch 8.3 only --- I fixed this in HEAD as part of recent locations patch.
