less required ADQL support [TAP-1.1]

[Patrick Dowler]

NoSQL was an example of the kind of thing this is about... and you could 
be right that the status quo is sufficient.

My impression was that this was something that people outside the ivoa 
looking in were interested in and that it could make it clear that TAP 
was the solution they needed even without a RDBMS. Realising that you 
can get away with a subset of ADQL and do something valuable is 
something people usually discover by committing to TAP and then just 
trying to do it... but the big projects that CSP is interested in 
satisfying are maybe not likely to do that.
