I've discovered another bug in the 'union interpretation' rule.

Consider the case:
    define type TN1 { T1 }
    define type TN2 extends TN1 { T2 } 
    define type TN3 restricts TN2 { T3 }

The union interpretation of TN1 should be:
    T1 | (T1,T2) | T3

but the rule results in:
    T1 | (T1,(T2|T3))
i.e.
    T1 | (T1,T2) | (T1,T3)
