You're right, this is a weakness in the spec., as Asir confirms: the
schema for schemas should (indeed I thought it already did) rule out
min/max on the top all/choice/sequence of a model group definition.

The schema for schemas already rules out min/max on the group
definition itself.

The logic is as follows:  min/max clearly _does_ make sense on a
<xs:group ref='...'/> in a model.  So we give precedence to that
min/max, and rule out any other min/max at the top levels of the
referenced group.

I'll fix the schema for schemas.
