The proposal is encoded as a TEI P5 document, and split into several parts. The common part defines the features used for describing the morphosyntactic properties of the languages. In this it follows the MULTEXT table format, which defines attribute-values pairs, with their respective codes used to mark them in the lexicons. The common part is followed by language particular parts, each giving the details about a particular language.
This representation, with the concrete applications which display and exemplify the attributes and values and provide their internal constraints and relationships, makes the proposal self-explanatory. Other groups can easily test the specifications on their language, simply by following the method of the applications. The possibility of incorporating idiosyncratic classes and distinctions after the common core features makes the proposal relatively adaptable and flexible, without compromising compatibility.
