- use of http type of access to xml db (Maciej's recent implementation; 
I remember he sent to the mailing list the results of performance tests 
of it)
- when fetching from the metadata configuration file (getting the key) 
only one xquery is used (previously 2 xpath statements were sent; so now 
we've got only one connection to xml db instead of two)
- when xml db is not configured as a storage the metadata configuration 
file is parsed only once and kept in memory as an object (this object 
can be used for fetching data using xquery/xpath)
