ADQL-0.9; another review & comment, please

[Ed Shaya]

Wil,
    What would be the advantage of approving a standard that is likely 
to change in a month or two.
    I would think the whole point of a standard is to agree to not 
change it for some reasonable length o f time, at least 6 months.
    Projects under duress to get something working in the next few 
months can use 0.7.4 without it being blessed as a standard. But if it 
looks like 0.9 is coming  right away or, if we let Tony have another 
look at it and then bless it, then either way 0.7.4 is going away too soon.
