The literal answer is "no", computed types/co-constraints are not supported in general. If you don't mind using the name "xsi:type" (with an appropriate namespace) instead of "position", then you can do this. Define types called 'first', 'middle' and 'last', then define <row> to have a type definition which subsumes all of them, and write e.g. <tableName xmlns:xsi="http://www.w3.org/2001/XMLSchema"> <row xsi:type="first"> . . . </row> <row xsi:type="middle"> . . . ht -- Henry S.
