MEF — Clause 9.2.2 Operation “applyMetamodel()

In the second sentence, suggest removing the phrase “an instance of”. Also, the description lacks instruction how to establish relationships between existing metaclasses and metaclasses introduced by applying a metamodel, and how to handle non-metaclass items, like data types contained in the applied metamodel.
