Can any enlightened monk tell of or advise on the wisdom of representing an entire database schema in XML, such that such various aspects of the database schema could be read via some wrapping object?

The primary intention of this would be to be able to specify, within this XML schema document, rules/regular expressions which define what values are allowed to be inserted into each column/field in the database.

I am presently looking into this kind of approach for an web-based, data-entry/display application. on the surface, this seems like a nice approach -- abstracting the syntactical validation of user input and (eventually) the data representation in a configurable file. However, i can't help feeling like someone must have done something like this before... though so far my searches have come to nought.

Would anyone have any links or advice as to whether this is a good idea? there may be a new cpan module brewing...

thanks,
