It is certainly legal per XML and XSD specs, and the SQL/XML spec has

mind-bogglingly impenetrable, though. Perhaps Peter or Nicholas might
know.
I think we can of course add our own annotations. It would be good to
go through the SQL/XML standard document and check what style they use
for their annotations so that we can structure and name ours similarly
and have room for future work, in case someone also wants annotations
for table names, schema names, etc. (Or was that part of your project as
well?)
Well, the standard has an element specifically for annotations
concerning certain objects: sqlxml:sqlname. However, I am not sure if it
can be used in this context. Can you try reading the standard
(<http://www.sqlx.org/SQL-XML-documents/5FCD-14-XML-2004-07.pdf>) and
tell me? :-) If it's not comprehended by the standard then we should at
least use a different namespace, and probably a different element name.
The style can be made to match, though.
I certainly think we could do more of this, although the column names
are what matter to me right now. We can also do it bit by bit.
cheers
