This is a known problem.  It actually causes a bug because we don't look up the qualified type appropriately during template instantiation.  The eventual AST representation will probably be what you suggest, that the child type will be allowed to be a QualifiedNameType or (dependently) a TypenameType, and template instantiation will just have to treat these cases differently.
