I think the answer to the question "should XML databases have their own classes or be implemented under DB or MDB" is "both". The former classes are for programming when one wants to take advantage of the special features of XML databases, the latter are when one has some existing code that uses DB or MDB for storage. Both might be used alongside one another on a single project, for example if you were writing a new application on top of an XML database but you want to use Mail::Queue at the same time. Having both sets of classes means a single underlying database can be used. Nigel Armstrong
