" As I think about this, wouldn't you want to implement constraints using program logic whether constraints are DB defined or not, in order to validate data prior to &amp;quot;insert&amp;quot; or &amp;quot;update&amp;quot;, and to provide appropriate error messages to users? What if you have say 12 RI constraints defined in the DB for a given record, what is an appropriate error message? -Nathan "^^<http://www.w3.org/2001/XMLSchema#string>
