Yes, these are actually the offerings of krb5. So the context is the
network and not the MAC system.

Agree, "local" seems to be used instead of "its". Changed most of the
occurrences of "local".

Ok, I had already changed this to be:
In this case, a mixed and loosely administered network is assumed,
where nodes may be running a variety of operating systems with
different security mechanisms and security policies. It is desired
that network file servers be simply capable of storing and retrieving
MAC security labels for clients which use such labels. The LNFS
protocol would be implemented here solely to enable transport of
MAC security labels across the network. It should be noted that in
such an environment, overall security cannot be as strongly enforced
as when the server is also enforcing, and that this scheme is aimed
allowing MAC-capable clients to function with its MAC security
policy enabled rather
than perhaps disabling it entirely.
But, in your registry document, we planned to reserve a LFS of 0 to mean
that the server is only capable of storing and returning labels.
