[SysML-1.6] The ElementGroup stereotype provides a lightweight mechanism for grouping various and possibly heterogeneous model elements by extending the capability of comments to refer to multiple annotated elements.

[SysML-1.6] Element groups can be members of other element groups, but this does not imply that members of the first are members of the second.

[SysML-1.6] The semantics of ElementGroup is modeler-defined. In particular, the body text is not restricted. It can describe the grouped elements as well as elements or values related to the grouped elements.

[SysML-1.6] Optionally, members of an element group can be ordered using its orderedMember property.

[SysML-1.6] Element groups do not own their elements and thus an element can participate in an unlimited number of groups.
