This is not hairsplitting -


  <!ELEMENT association
      ( instanceOf?, scope?, member+ )
   >

<!ELEMENT scope  ( topicRef  | resourceRef | subjectIndicatorRef )+ >
<!ELEMENT instanceOf  ( topicRef | subjectIndicatorRef ) >
<!ELEMENT member
      ( roleSpec?, ( topicRef | resourceRef | subjectIndicatorRef )+ )

<!ELEMENT roleSpec  ( topicRef | subjectIndicatorRef ) >

In xtm 1.0, an association may have a scope, while a member (i.e., role) 
may not.  No hairsplitting.
