Here's why we haven't... :)
ZeeRex is a Service Description (eg it describes machine to machine
service interfaces) not a Collection Description (eg it doesn't describe
the sort of items that you can find using the service).
Where the service keeps its collection is entirely outside of the scope of
ZeeRex as a service description, but if desired it could be included in
the human readable 'description' field in databaseInfo, or links to the
remote services in databaseInfo/links/link elements.
