syslog Structured Data ID Values

-
IETF Review
- Reference
- [RFC5424]
- Note
-
The registration rules for this registry will be that new Structured Data ID values and new Parameter Name values must be registered via IETF Review. In addition, once SD-IDs and SD-PARAMs are defined, the syntax and semantics of these registrations must not be altered. In the event that modifications of existing registry items are required, a new SD-ID or SD-PARAM must be created, leaving the older one unchanged. Finally, the IANA does not register, and will not control SD-IDs or SD-PARAMs \with an "@" sign (ABNF %d64) in them.
