I don't realy see the point, why tap ADQL to the registry ?
There is actualy two method : search and keyword search.
 From my point of view, searching in the registry has nothing to do with 
searching in a data service. The complexity of ADQL make only the job 
much more complex to implement.
We should realy think of a search method in the registry based on very 
limited SQL (LIKE, WHERE, AND , OR) inside a search and keyword search.
maintaining XML schema will allow xml databases or mixed one (Postgresql 
including xpath).
Pushing TAP to that will increase much more the implementation 
complexity for no real useful feature.
