Coming back from vacation, I've added some comments to the wiki page
and added what I think Paul's point are in two places -- so, Paul, if
I misrepresented you, sorry.

Executive summary of my changes:

I'd really like to see a TAP/ADQL interface to searchable registries,
but we shouldn't forget that there is OAI-PMH and VOSI.  We may want
some IR/Text-Searching user defined function if we go ahead and use
ADQL as the query language.  And, we really should keep XML
(unfortunately XSD-defined) as the primary format of VO resource
records, if only for interoperability with other bibliographic
engines.

Cheers,
