If I understand the thinking correctly, it is that a database would be
represented by a virtual document containing a list of the instance
documents, identified by URL; and then yes, you should be able to search
this entire collection. Of course XSLT has that capability too (in theory):
the real challenge is designing optimizers that can take advantage of
persistent indexes, etc.
