Clarifications

1 An association between two <DRM Feature> instances indicates that they are alternate representations of the same environmental object.

2 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.

3 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.
