This document updates RFC 7252 by modifying the registration
procedures for the "CoAP Content-Formats" IANA registry, within the
"Constrained RESTful Environments (CoRE) Parameters" registry group.
This document also introduces a new column, "Media Type", to the
registry. Furthermore, this document reserves Content-Format
identifiers 64998 and 64999 for use in documentation.
This document is a product of the Constrained RESTful Environments Working Group of the IETF.
This is now a Proposed Standard.
