Re: difference in design

Abe,

Michael is no doubt talking about an XML Schema whereas your application 
presumably has a SQL Schema, which through some proprietary transformation 
allows a valid XML representation of the data.

Officially SQL schemas are outside of the scope of this list, but someone 
might have experience with the setup you have.

>From a purely XML point of view, both XML examples are well-formed and at 
that level are of equal merit.
