ADQL schema versions

Hi all,

Can we agree where the ADQL schemas are going to be posted so that we can find them in one place? They should be versioned too, say in the schema name itself (eg ADQL-v0.5.xsd, ADQL-v0.6, etc). That way we don't suddenly break tools when the schema is updated, and it helps when parsing query documents as we can work out which version has been submitted. In the meantime I have made some guesses at versions and posted them here:

http://wiki.astrogrid.org/pub/Astrogrid/AdqlNotes/ADQL-v0.5.xsd - from the SkyService ADQL definition page.

http://wiki.astrogrid.org/pub/Astrogrid/AdqlNotes/ADQL-v0.6.xsd - from the SkyService Translator page

Also - why is there such a difference between them? I can understand our own human-added elements changing (eg XMatch and Area) but if the rest of it is automatically generated why is it changing?

Cheers,

Martin
