This work presents results on the integration of frame-based representations into the framework of eXtensible MetaGrammar (XMG). Originally XMG allowed for the description of tree-based syntactic structures and underspecified representations of predicate-logical formulae, but the representation of frames as a sort of typed feature structure, particularly type unification, was not supported. Therefore, we introduce an extension that is capable of handling frame representations directly by means of a novel <frame>-dimension. The aim is not only to make possible a straightforward specification of frame descriptions, but also to offer various ways to specify constraints on types, be it as a contiguous type hierarchy or a loose set of feature structure constraints. The presented extensions to XMG are fully operational in a new prototype.
