Definition

The means of accessing an <DRM Attribute Set> that is contained in a <DRM Attribute Set Table>.

The <DRM Attribute Set Index> contains an index into the primary <DRM Attribute Set Table> of <DRM Attribute Set Table Group> to which it is associated. The <DRM Attribute Set Table Group> specifies which of its <DRM Attribute Set Table>s is being used, while the <DRM Attribute Set Index> specifies which <DRM Attribute Set> within that primary <DRM Attribute Set Table> is being referenced.

Example(s)

· Consider an <DRM Attribute Set Table Group> whose primary <DRM Attribute Set Table>'s kth <DRM Attribute Set> consists of <DRM Colour>s and <DRM Image Mapping Function>s for sandy ground under normal, Out the Window (OTW) viewing conditions.

A terrain <DRM Polygon> that references this set will do so by having an <DRM Attribute Set Index> component that is associated to the <DRM Attribute Set Table Group> and whose index value is set to k.
