It's also worth mentioning that you can use a similar technique with 
attributes.

For sets of attributes, use <empty/> instead of <notAllowed/>

<define name="i18n.attributes">
   <empty/>
</define>

> Individual files usually say something like

>       <!-- CM -->
>     </element>
>   </define>

Then use combine="interleave" instead of combine="choice".

<define combine="interleave" name="i18n.attributes">
   <attribute name="xml:lang">
     <data type="language"/>
   </attribute>
</define>
