Attributes and Scope

Is there an easy way to have a NodeAttribute affect the Scope of the attributed node?  Would making the attribute implement ScopeProvider on the NodeAttribute work?

Basically, what I'm trying to do involves putting an attribute on a Classifier, and other NodeAttributes on members of the classifier.  The member's attributes have values that depend on the classifier's attribute. 

I can write an appropriate scope for this in the Constraints, but if I could just use ScopeProviders and inherited scopes, that'd seem to be much cleaner to me.
