My Bad , Got posted the incomplete question . So let me complete .

What I want is the XSD/DTD for the above XML that ensures that the position attribute vale is always unique i.e. if an XML <field> has the position as 1 no other <field> should have that value.

Can we ensure this using XSD/DTD.

Thanks

Unique constraint in xsd will help you do this.
