<p>Because link-local communication does not involve the exchange of XMPP presence, it is not possible to use &xep0115; for capabilities discovery. Therefore, it is REQUIRED to instead include the node and ver TXT records (and OPTIONAL to include the ext TXT record). The values of these records MUST be the same as the values for the 'node', 'ver', and 'ext' attributes that are advertised for the application in XMPP presence (if any) via the Entity Capabilities protocol as described in <cite>XEP-0115</cite>.</p> <p>Because link-local communication does not involve the exchange of XMPP presence, it is not possible to use &xep0115; for capabilities discovery.
