But if NSI wants to use paths/links as connected ports because of some
reasons then I woul be open to let them do it this way. Other
users/applications may prefer using links because of some other reasons.
By setting the limits should we prevent various users/applications from
utilizing NML? Do we want to be so strict? Extensions (namespaces) and
minimal set of rules would be an answer.
