* - a global enumeration, one that's executed across all providers
* - a provider-specific enumeration, one that's only executed by a single

* - a context enumeration. I know this contradicts what I just said about
* there being no correspondence between the scope and the type, but it's
* necessary for the special case that a "Entire Network" entry needs to
* be enumerated in an enumeration of the context scope. Thus an enumeration
