By using ruby I ll force many average users into trouble, from a practical point of few, and by using a java server I'd extend that much more. so this is no option to me anyway :<. > I found a confusion mapping OO to XML, are the element names roles or > types?

I am not familiar with "roles and types" in this regard - so I dont know what you are talking about, but by your example I thought, do you mean the distinction between datatypes/datacontainers and data/dataelements?
