Description: The human-readable name of a service. Where appropriate, as in the case where a service can be identified in terms of a single protocol, the strings should be established names such as those assigned by IANA and found in STD 2 [13], or defined by some other authority. In some cases private conventions apply and the string should in these cases be consistent with these non-standard conventions. An applicability statement may specify the service name(s) to be used.
