Thanks for the response Alexander, though I'm specifically looking
for what case causes EOModeler to DISABLE these options. If you go
into the inspector in EOModeler, under certain cases, one or the
other of those checkboxes is grayed out. I'm sure if I thought about
this for a bit it would make sense, but I was hoping someone knew
offhand what triggers that.

Propagates Primary Key: the target of the relationship is (part of)
a primary key that is not generated but just a copy of the source
primary key. (eg. m:n, 1:1)
Owns Destination: if the target is removed from this relationship
and not reinserted into another (and therefore is unreacheable), it
will be automagically deleted on saveChanges - without a need to
explicitly call deleteObject.

Anyone happen to know the rules that determine when Propagates
Primary Key and/or Owns Destination become enabled and disabled in
EOModeler?
