This is correct.

This will cause trouble, as it cannot be extended as follows (call
your type above 'base':

 <complexType mixed="true">
  <complexContent>
   <extension base="base">
    <sequence>
      <element ref="elt"/>
    </sequence>
   </extension>
  </complexContent>
 </complexType>

but this is in fact OK.
