Superclass

·         <DRM Base Summary Item>

Class

·         <DRM DRM Class Summary Item>

Subclass

·         none

Definition

An object of this DRM class is used as part of a summary of a transmittal's content by representing a class that is used within the transmittal.

<DRM DRM Class Summary Item>s are combined together to form a list of the classes that are used in a transmittal or part of a transmittal. Each such list has only one entry per class. However, it does not have to be a complete list of every class used, and it can include abstract classes.

Each <DRM DRM Class Summary Item>s can optionally have a list of <DRM EDCS Use Summary Item>s giving the classifications that are attached to objects of that class in the transmittal. Obviously this only makes sense for those classes that can have classification information.

Each <DRM DRM Class Summary Item>s can also have a list of <DRM SRF Summary>s giving the SRFs defined in the transmittal by objects of that class. Obviously this only makes sense for those object types that contain coordinate system definitions.

Example(s)

·         A summary of the object types used in an entire transmittal. 

·         A summary of object types used in part of a transmittal.
