This is a good way to describe it. It's a relationship in that it requires other components for it to have substance; and it's also a standard applying to behavior.
But what broad 'types' are there, I think, is the question. Aside from the ones he mentions (those that enable coexistence and those that protect & secure 'ownership'), what might the others be?
Everything is either form or relationship...Every form is a standard..You get married..It is a form, and a formality, so there is a certain standard of behavior that comes with it...It can be a sort of power structure like law, and it can become a way of achieving justice, or denying justice...You cannot say marriage is law, and yet it is legal, and law is a form as marriage is with a certain relationship associated with it... You can get the big picture...You can see everything as two thing, and see those two things in terms of the other...Then the essential question is no longer what it is; but what it does, why it does, and why it fails, and why it cannot do later what it was once able to do... As people change, so change their form...As societies change, so change their forms...When societies change they change through a change of forms... Ideology was once a subject of study, so that Napoleon called them ideologues, talkers rather than doers.. If we as human beings will master our futures and all our futures we must master forms, grasp their significance and turn them to our benefit...Now, one man who was clearly a man of his day, of the enlightenment, Thomas Jefferson talks about forms in the Declaration of Independence...Incidentally, he was an Attorney...All we do is form... All we are is form... Law no sooner fails humanity and is torn down than it is built up again...Why??? What do people expect from the form???
