Right. Which means, I assume, that the link between RIF "payload 
identifiers" and the applications shared data model goes through the sorts?

Could we dig a little bit more into that? Suppose the parties 
interchanging the rule that contain your example have agreed to 
interchange data according to an XML Schema that defines (not sure it is 
correct, but you get the idea):

<complexType name=person>
   <complexcontent>
     <element name="name"/>
     ...
   </complexcontent>
</complexType>

<compleType name="item">
   ...
</complexType>

<complexType name="purchase">
    <sequence>
       <element name="buyer" type="person"/>
       <element name="seller" type="person"/>
       <element name="purchasedItem" type="item"/>
    </sequence>
</complexType>

How would that mix with the RIF XML syntax if they want to interchange a 
rule that contains you example condition?
