Issue 13870: Question on InvertibleAttribute subclass of ExplicitAttribute (express-rtf)

Source: TopQuadrant (Mr. David Price, dprice(at)topquadrant.com)
Nature: Uncategorized Issue
Severity:
Summary:

It seems an odd thing to me to create a subclass of ExplicitAttribute to 
instantiate for Attributes that have the potential to have inverses. I don't 
understand the rationale. Seems like it would be simper to have a constraint 
on InverseAttribute about it being owned by an EntityType referenced in an 
ExplicitAttribute
