A bug in RIF? God gracious!

You mean, that solution, as opposed to simply correcting the bug in the 
XSD, e.g., for Core and PRD:

 <xs:element name="List">
   <xs:complexType>
     <xs:sequence>
       <xs:group ref="IRIMETA" minOccurs="0" maxOccurs="1"/>
       <xs:choice minOccurs="0" maxOccurs="unbounded">
         <xs:group ref="GROUNDTERM"/>
       </xs:choice>
     </xs:sequence>
   </xs:complexType>
 </xs:element>

I do not remember why we did not do it like you propose, the first time, 
though it would have been consistent with what we did everywhere else.

Was there an identified problem with having an (ordered) "items" role 
containing the list elements?

(Not that I object: actually, I did not even remember that we did 
otherwise; but I am just wondering _why_ we did otherwise).
