There are 2 messages on the comments list requesting more powerful xs:all 
[1][2]. There is another comment on xs:all [3] complaining about our 
limitations on xs:all.

Basically the 2 messages are asking for 3 enhancements:
1. Allow maxOccurs>1 on elements inside <xs:all>
1.1 And require that same named elements in the instance have to be 
together (no interleaving). That is, A,A,B,B,B, instead of A,B,B,A.
2. Allow <xs:all> to appear inside <xs:sequence> and <xs:choice>
3. Allow xs:all extensions, to add new elements into all model groups.
