Why so ? What's wrong with a plain SQL file ? We already have a language 
for RDBMS schema description, and the schema description is itself 
stored in the RDBMS catalog so the SQL description can be regenerated 
from the RDBMS. I just don't see the point of storing all this in XML.

SQLAlchemy is an interesting attempt at integrating the relational model 
in a programming language.

Ok, I don't mean neither of us is necessarily right and the other wrong 
- different POV, mostly, so I guess we can at least agree to disagree !-)
