        Standard,
        TCollection,
        gp,
	TColgp,
	TColStd,
	Message,
        Interface,

is

        class SubfigureDef;
        -- Type 308,    Form 0
        ---Purpose : Permits a single definition of a detail to be 
        --           utilized in multiple instances in the creation 
        --           of the whole picture.

        class Group;
        -- Type 402,    Form 1
        ---Purpose : Allows a collection of a set of entities to be 
        --           maintained as a single entity.

        class GroupWithoutBackP;
        -- Type 402,    Form 7
        ---Purpose : Allows a collection of a set of entities to be 
        --           maintained as a single entity, but without back 
        --           pointers.

        class SingleParent;
        -- Type 402,    Form 9
        ---Purpose : Defines a logical structure of one independent
        --           (parent) entity and one or more subordinate 
        --           (children) entities.

        class ExternalRefFileIndex;
        -- Type 402,    Form 12
        ---Purpose : Contains a list of the symbolic names used by the
        --           referencing files and the DE pointers to the
        --           corresponding definitions within the referenced file

        class OrderedGroup;
        -- Type 402,    Form 14
        ---Purpose : Allows a collection of a set of entities to be
        --           maintained as a single entity, but the group is 
        --           ordered.

        class OrderedGroupWithoutBackP;
        -- Type 402,    Form 15
        ---Purpose : Allows a collection of a set of entities to be 
        --           maintained as a single entity, but the group is 
        --           ordered and there are no back pointers.

        class Hierarchy;
        -- Type 406,    Form 10
        ---Purpose : Provides an ability to control the hierarchy of each
        --           directory entry attribute.

        class ExternalReferenceFile;
        -- Type 406,    Form 12
        ---Purpose : References definitions residing in another file.

        class Name;
        -- Type 406,    Form 15
        ---Purpose : Used to specify an user defined name.

        class AssocGroupType;
        -- Type 406,    Form 23
        ---Purpose : Used to assign an unambiguous identification to 
        --           a Group Associativity.

        class SingularSubfigure;
        -- Type 408,    Form 0
        ---Purpose : Defines the occurrence of a single instance of the 
        --           defined Subfigure.

        class ExternalRefFileName;
        -- Type 416,    Form 0-2
        ---Purpose : Used when single definition from the reference file is
        --           required or for external logical references where an
        --           entity in one file relates to an entity in another file

        class ExternalRefFile;
        -- Type 416,    Form 1
        ---Purpose : Used when entire reference file is to be instanced

        class ExternalRefName;
        -- Type 416,    Form 3
        ---Purpose : Used when it is assumed that a copy of the subfigure
        --           exists in native form on the receiving system

        class ExternalRefLibName;
        -- Type 416,    Form 4
        ---Purpose : Used when it is assumed that a copy of the subfigure
        --           exists in native form in a library on the receiving 
        --           system
