Done. I changed the name of the simple type to ElementReferenceType for 
consistency with the other types in the wsdl namespace.

The type declaration now looks like this:

   <xs:simpleType name="ElementReferenceType">
     <xs:union>
       <xs:simpleType memberTypes="xs:QName">
         <xs:restriction base="xs:token">
           <xs:enumeration value="#any"/>
           <xs:enumeration value="#none"/>
         </xs:restriction>
       </xs:simpleType>
     </xs:union>
   </xs:simpleType>

By the way, in section 2.5.3 you should add an "Otherwise empty." at the 
end of:

   {message content model} 	If the element attribute information
   item is present and its value is a QName, then #element. Otherwise the
   actual value of the element attribute information item, if any.
