Hi Fabio,

Thank you for this. There will be one TAP standard and I withdraw my 
proposal. The good thing is that Pat's proposed restructuring can 
deliver the best of both worlds; a TAP standard we can finalise quickly 
and full support for ADQL and Parametrised Querying in a concise and 
resilient format. We must consider it seriously.

The work that remains is to finalise the Service Interfaces, the 
mandatory and optional query forms and to resolve the 
VODataService/VOTable issue raised by François and Guy. Whatever we 
decide, these three items have to be resolved. The course we choose now 
will strongly influence the quality of the final result.

Keith.
