ClassDeclaration
ClassDeclaration defines the structure (model/schema) of composite data. It is composed of a set of Properties, may have an identifying field, and may have a super-type. A ClassDeclaration is conceptually owned by a ModelFile which defines all the classes that are part of a namespace.
