  RFC 1123
  
     <networking, standard> The RFC "Requirements for Internet
     Hosts Application and Support" which clarifies or changes the
     specification of protocols given in earlier RFCs.
  
     RFC 1123 defines the terms "MUST", "SHOULD", "MAY",
     "unconditionally compliant", "conditionally compliant".
     Capitals are used to emphasise that the official definition of
     the word is being used.
  
     MUST or REQUIRED means an absolute requirement for
     conformance.
  
     SHOULD or RECOMMENDED means the item can be ignored under
     certain circumstances, although the full implications should
     be understood.
  
     MAY or OPTIONAL means the implementor can choose, usually
     depending on whether it is needed or not.
  
     Something "unconditionally compliant" meets all the MUST and
     SHOULD requirements, "conditionally compliant" meets all the
     MUST requirements and "not compliant" - does not meet some
     MUST requirement.
  
     For example, RFC 1123 amends RFC952 to say software MUST
     handle either a letter or a digit as the first character of a
     hostname.
  
     (rfc:1123).
