Advantages of my proposal are very significant, while your 
concern is merely for consistency.

I have two completely different answers.  One of them requires whole-sale 
reengineering and I will write more about it in a different thread.
This mail covers the other answer (which is not my favorite).

We have already prohibited

<zeroOrMore>
  <group>
     <attribute><anyName/></attribute>
  </group>
</zeroOrMore>

but have allowed

<zeroOrMore>
  <attribute><anyName/></attribute>
</zeroOrMore>

In other words, we already have "incosistency".  Why bother?
