Great, glad to hear it. I've learned a bit myself ;-)

Apparently not. You just need to supply enough information about the
name of the schema (which gets passed as the systemId argument to
resolveEntity()) so that you get get what you need from your DB.

Right. The parser will invoke resolveEntity() and it will pass the
value of the *SchemaLocation attribute as the systemId argument. So
your entity resolver needs to be able to take the system ID with that
information create the appropriate schema from your DB, and return a
MemBufInputSource to the parser.
