3.1.1.2.1 Required Native Categorizations

Unless specified here, the NSPI Protocol does not constrain the categorization of properties, and clients and servers MUST NOT require specific categorizations. However, because the protocol intends for clients to be able to persist sorted string values across multiple NSPI connections to an NSPI server, a server MUST NOT modify its native categorization for string properties once the categorization has been determined, as doing so would lead to inconsistent behavior of NSPI methods across multiple NSPI sessions.

The following table specifies those properties whose categorization is specified by the NSPI Protocol, and the categorization of those properties.
