[TAP] MAXREC

[Patrick Dowler]

A small question about using MAXREC=0. The draft states that this produces an 
output table if the query is (will be) otherwise successful, eg a valid query. 
Should this be a valid query (meaning it tests the actual ADQL query, which is 
probably only do-able by running it) or just a valid request?

The complication with the valid query interpetation, as I see it, is that 
practically one would have to at least create uploaded tables, which means at 
least transferring and parsing the input VOTables and then parsing and running 
the query on the database, as many checks and errors will be deferred to that 
stage.

With PQL a "valid request" is more or less synonymous with "valid query" so it 
is not much of an issue there. 

Thoughts?
