I'm not sure how a base layer that is not streamable can have a layer added 
to it that makes it streamable.  Am I missing something?

And my two cents on other issues...
- Restricting the range of integers and length/patterns of strings seems 
useful for the base layer.
- I don't think arbitrary values for minOccurs/maxOccurs (as opposed is ?, , 
*, and +) are a problem.

Which really points to different people wanting different things so 
sub-setting XSD into layers is going to be a problem.  It's probably best to 
start afresh.  I that respects I agree with Michael's sentiments of letting 
XSD 1.1 go forwards and then working on something new.
