0.7.1 vs 0.7.3 AND cardinality AND ...

I've glanced at all the recent messages but won't have time to digest them until next week when I hope to take time to look at the two versions in detail - can we hold off until then on deciding which to use.

On the issue of cardinality it seems simple: either we simplify the ADQL/x from what is automatically generated or we don't. If we agree to a simpler schema than the generated one then it is daft not to allow cardinality of 2..* for ANDs, ORs etc. **This does not change anything about the language or how it is interpreted in any way!** It is ONLY a matter of simplifying how any query is _represented_ in xml form.

To me the choice is: do we want to simplify the representation of a query in xml or not? If no, then we stick with 0.7.1; if yes, then cardinality of 2..* has to be included in 0.7.3.

Now back to AstroGrid-2!

Cheers,
Tony.
