ElementAspect Class

An Element Aspect is a class that defines a set of properties that are related to (and owned by) a single element. Semantically, an ElementAspect can be considered part of the Element. Thus, an ElementAspect is deleted if its owning Element is deleted. BIS Guideline: Subclass ElementUniqueAspect or ElementMultiAspect rather than subclassing ElementAspect directly.
