Definition

An instance of this DRM class specifies an interchangeable group of one or more <DRM Property Set Table> instances. The primary <DRM Property Set Table> in the group is indicated by the primary_table_index. When a reference is made to an <DRM Property Set Table> (for example, from an <DRM Property Set Index> component of a <DRM Polygon>), the reference identifies the <DRM Property Set Table Group> and the index within the <DRM Property Set Table>, but not the specific <DRM Property Set Table> within the <DRM Property Set Table Group>. By definition, an <DRM Property Set Index> refers to an <DRM Property Set> from the primary <DRM Property Set Table> of the indicated <DRM Property Set Table Group>. An alternate <DRM Property Set Table> from within the <DRM Property Set Table Group> can be chosen at the discretion of the data consumer.

Clarifications

¹ This 1-based index specifies the primary <DRM Property Set Table> component from the ordered <DRM Property Set Table> components of the given <DRM Property Set Table Group> instance.

Example(s)

One <DRM Property Set Table Group> in the transmittal, and that group has only one <DRM Property Set Table> within the group. That <DRM Property Set Table> is the one and only <DRM Property Set Table> for the entire transmittal.
An <DRM Property Set Table Group> with two <DRM Property Set Table> components, one for normal, Out The Window (OTW) viewing, the other to change the appearance of the view to be a view as seen through Night Vision Goggles (NVG).
An <DRM Property Set Table Group> with 3 <DRM Property Set Table> components with the same usage of OTW. Why 3 tables? One <DRM Property Set Table> defines the colours and textures as originally created by the data modelers. The second <DRM Property Set Table> has different shades of blue for the lakes and skies because a company VIP came through and didn't like the blues that were there. The third <DRM Property Set Table> contains yet another set of blues for the lakes, different textures for the lakes and different shades of green for the trees and tanks, because the customer in charge of the program came through and didn't think the colours and textures were realistic.
