resuming progress on TAP

[Christophe Arviset]

Dear all

I also fully support this approach. From a technical point of view, as 
indicated already by various people, it makes sense to keep 
specifications focus and simple and not to try to mix various things 
into a same standard. Having a common ParamQuery specs would also be a 
benefit for other DAL specs overall.

It's good to see that people now seem to be converging on this point so 
we can move forward.

Cheers
