Clarifications

1An association between two <DRM Feature Representation> instances indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship.

2An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship.

3An association between a <DRM Property Grid> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) represented by the <DRM Feature Representation> instance and the <DRM Property Grid> instance (or some specific cell data within that <DRM Property Grid> instance) have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. Each associated <DRM Property Grid> instance indicates whether the entire <DRM Property Grid> instance or only some specific cell data within it is participating in the relationship in question.

4An association between two <DRM Feature Representation> instances indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship.

5An association between a <DRM Geometry Hierarchy> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) that they represent have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship.

6An association between a <DRM Property Grid> instance and a <DRM Feature Representation> instance indicates that the environmental object(s) represented by the <DRM Feature Representation> instance and the <DRM Property Grid> instance (or some specific cell data within that <DRM Property Grid> instance) have the semantic relationship indicated by the <DRM Base Association Data> link object on the association relationship. Each associated <DRM Property Grid> instance indicates whether the entire <DRM Property Grid> instance or only some specific cell data within it is participating in the relationship in question.

7These components support attributes for derived objects; that is, they are used only to specify texture mapping information for geometry that is derived from the <DRM Primitive Feature> instance by the consumer. These <DRM Image Mapping Function> components shall use <DRM Image Anchor> components to specify the mapping.

8The <DRM Presentation Domain> component is needed because, in many cases, a <DRM Primitive Feature> instance may be significant only for a particular domain, such as radar.
