The two instances are referred in the context of "namespace" (collection of classes and properties to express things in common domain), not "profile" (conformance point).

Current:

There are two associated profiles, the SimpleLicensing profile and the ExpandedLicensing profile. Both allow expression of the same information, albeit in different ways.

Proposed:

There are two associated namespaces, the SimpleLicensing namespace and the ExpandedLicensing namespace. Both allow expression of the same information, albeit in different ways.

Also rename "profile" in diagram page to "namespace" as well,
as the diagrams only show classes and properties, not profile constraints.
