A restriction may have a simpleType as its first child. But is the following
fragment of a schema allowed?

<simpleType name="test">
 <restriction>
  <simpleType>
   <restriction>
     <simpleType>
       <restriction base="long"/>
     </simpleType>
    </restriction>
  </simpleType>
 </restriction>
</simpleType>

It doesn't seem that this would allow any more expressivness than one level
of restriction. Is there someplace in the Rec' that disallows this
structure? Is there some extra expresiveness that can be obtained by using
it?

Tnx
