Re: Trying to Understand Complex Abstract Types: How To Define?

You're on the right track as far as I can see, although your use of
xsi:type if meant literally is probably not what you want.

In particular, in the absence of content models expressed in terms of
types alone, use abstract elements and substitution groups.

George Bina's reply gives a good example of how this would look.

If you want to constrain the specialisztions to be restrictions
(resp. extensions), include final='extension' (resp. 'restriction') in
your type definition for InformationModule.
