Boxes and Polygons in ADQL/STC. Questions and recommendation.

[Roy Williams]

It seems that the region specification does not support the RA/Dec 
limits, or the Glon/Glat limits, etc etc. All polygon boundaries in ADQL 
Region are great circles.
-- Is that correct?

Therefore I assume the recommendation will say that such regions should 
NOT be implemented with ADQL Region, but should be implemented directly 
in the SQL query like this:
    RA between 200 and 210 and Dec between 20 and 30.
