------- Additional Comments From cmsmcq@w3.org  2005-12-09 20:45 -------
The WG discussed this item on 9 December 2005 and agreed to treat
it as a requirement for 1.1 that we clarify whether anySimpleType
may or must not be used as a member of a union.

But 2574 raises the same question for version 1.0; it may be 
relevant to this issue because if 1.0 has a clear answer to
this question, some WG members will prefer not to change the
answer in 1.1.

There is a minor error in comment 1 -- it is clause 3.1 of 
Schema Component Constraint: Derivation Valid (Restriction, 
Simple), not Simple Type Definition Properties Correct, which
appears to rule out anySimpleType.

    3.1 The {member type definitions} must all have {variety} 
        of atomic or list.


This clause must change, however, in any case, since the
resolution of bug 2044 (retain union-level facets) requires 
that member types of variety union be allowed.  (See bug 2044 
comment 2, see also bug 2333, which is the Structures part of 
that issue.)
