Can XQL be used to query *multiple documents*? For example if I need
to search on all book elements having an author elements as Bob, then
will the query
book[author = 'Bob']
work on multiple XML documents say Doc1 .... Doc10. How do we specify
that the query needs to be done on these documents? What format will the
result be(result of an XQL quer is a well formed XML document ) In this
case will the result be one document ??
