Clarifications |
1 If a given <DRM Feature Volume> has an association relationship with a <DRM Feature Edge> instance, that <DRM Feature Edge> instance is contained within the <DRM Feature Volume>. 2 The <DRM Feature Face> instances that border a given <DRM Feature Volume> instance indicate the relationship by their association to the <DRM Feature Volume>. The converse of this relationship is that between <DRM Feature Volume Shell> and <DRM Feature Face>. 3 If a given <DRM Feature Volume> has an association relationship with a <DRM Feature Node> instance, that <DRM Feature Node> instance is contained within the <DRM Feature Volume>. 4 The first <DRM Feature Volume Shell> associated with a <DRM Feature Volume> instance is its external shell, while the remaining, if any, are its internal shells. Exception: Since the universal <DRM Feature Volume> has no external boundary, all of its shells are internal shells. The universal <DRM Feature Volume> can be identified by the fact that its universal field is set to TRUE. |
