<p>It is OPTIONAL to include any of these TXT keys, since link-local messaging can be used by non-human entities (e.g., devices) and these keys relate to human users. However, for use by humans, certain keys are of greater interest than others, e.g. the "msg" and "status" keys. See also the <link url='#security'>Security Considerations</link> section of this document regarding the inclusion of information that may have an impact on personal privacy (e.g., the "1st", "last", "nick", "email", and "jid" keys).</p>
