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.
