Sure it can. Some of Apple's examples show this. It's not really a
'pointer' so much as a reference to another instance of that entity
by its objectID (which boils down to a URI that looks like "x-
coredata://.....";), an archivable reference. Basically, yes, this is
perfectly legal and acceptable practice.

Is there some rule that says a entity's relationship can't include
a pointer
to itself?
