Type_fileformat is a subtype of Type_DOMS. Format hierarchies are possible; i.e. Type Fileformat defines the 'extendsFormat' relation (e.g. '24 bit baseline tiff' extendsFormat 'baseline tiff' extendsFormat 'tiff'). Type Fileformat also defines the TechnicalSpecification datastream. Say object A isObjectType Fileformat. Then when an object B isObjectType File and isFileFormat A, the TechnicalSpecification datastream in A describes the legal content of the Technical datastream in B.
