that would possibly work if there is a way for the enforcer to retrieve
scope information from the artifact - is this possible?

Is it also possible for transitive dependencies, i.e., will the enforcer let
me allow the same artifact to go through when using it as a transitive dep
of a test-scope artifact but at the same time disallow the same artifact
when it is used as the transitive dep of a compile-scope artifact?

I am unfamiliar with the API for custom enforcer rules and the documentation
on the maven site does not give me the level of detail I am looking for in
order to be able to answer these question easily myself.
