that however is very true. except i think phpcr does not have many_to_many ever. one_to_one is a referenceOne field, one_to_many is  referenceMany (multivalue) field, and many_to_one is a referrer field. afaict there is no many_to_many: while theoretically you can have multivalue reference and many referrers for that relation, i don't see how we could make the admin ever display that in a single form or list. joins? i wonder if we should keep many_to_many or drop it until we support it anywhere?

what do you think of explaining this (reference one / reference many / referrers) in the template files so people know from opening the files which is which?
