[regrep] RegistryObjectQuery

Illustration of changes in Filter Query needed in order to support
RegistryObject Query is attached. This is what Farrukh and me could do while
working on it briefly this morning.

I think that we should also address other comments that are posted w/r/t
"Query Proposal".
