11. No IPR Disclosures in IETF Documents


   IETF and RFC Editor Documents must not contain any mention of
   specific IPR.  All specific IPR disclosures must be submitted as
   described in Section 6.  Specific IPR disclosures must not be in the
   affected IETF and RFC Editor Documents because the reader could be
   misled.  The inclusion of a particular IPR disclosure in a document
   could be interpreted to mean that the IETF, IESG, or RFC Editor has
   formed an opinion on the validity, enforceability, or applicability
   of the IPR.  The reader could also be misled to think that the
   included IPR disclosures are the only IPR disclosures the IETF has
   received concerning the IETF document.  Readers should always refer
   to the on-line web page to get a full list of IPR disclosures
   received by the IETF concerning any Contribution.
