CAD systems often want groups to contain objects from several layers. A
"geometry" layer might contain objects that form the boundary of a
mechanical part and a "dimensioning" layer might contain the arrows,
dimensions, and annotations applied to the part. Groups would be used to
group the geometry of sub-parts; one for "bracket A", another for
"subassembly B", for example.

If SVG allows an object to be a member of more than one group, one can do
this.
