Definition |
A mechanism for specifying discrete states from a possibly continuous state value. Each discrete state corresponds to a branch of the <DRM State Related Features> and is identified by the <DRM State Data> for that branch; the state value itself is given by the state_tag of <DRM State Related Features>. |

Clarifications |
1 If this value is TRUE, each “descendant” of this aggregation - that is, each <DRM Feature> instance that exists in the component tree rooted at the given <DRM Aggregate Feature> - shall be unique, in the sense that it shall appear in only one “branch” of this aggregation. If unique_descendants is FALSE, at least one <DRM Feature> instance appears in more than one “branch” of the aggregation. 2 If this value is TRUE, each “branch” of this aggregation strictly complies with the organizing principle for its particular subclass. If this value is FALSE, at least one “branch” does not strictly comply with the given organizing principle. See the organizing principle constraint for each specific subclass for details. 3 This is the state by which the component <DRM Feature Hierarchy> instances are being differentiated, and shall be an EAC which is designated as “state applicable”. 4 This is the default state. If the given <DRM State Related Features> instance has a <DRM State Control Link> component, this field is the target of that <DRM State Control Link> instance. 5 An association between two <DRM Feature> instances indicates that they are alternate representations of the same environmental object. 6 An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature> instance indicates that the <DRM Geometry Hierarchy> and the <DRM Feature> are alternate representations of the same environmental object. 7 An association between a <DRM Property Grid> instance and a <DRM Feature> instance indicates that the <DRM Feature> and the <DRM Property Grid> (or some specific cell data within that <DRM Property Grid>) are alternate representations of the same environmental object. Each associated <DRM Property Grid> will indicate which is the case. 8 This relationship exists to support “attributes for derived objects.” That is, these components are used only to specify texture mapping information for geometry that is to be derived from the <DRM Aggregate Feature> by the consumer. These <DRM Image Mapping Function> instances shall use <DRM Image Anchor> components to specify the mapping. 9 This is needed for cases in which an <DRM Aggregate Feature> is significant only for a particular domain, such as radar. |
