Precedence: list

The following errata report has been submitted for RFC5795,
"The RObust Header Compression (ROHC) Framework".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=5795&eid=2109

--------------------------------------
Type: Editorial
Reported by: Alfred Hoenes <ah@TR-Sys.de>

Section: 5.1.2, pg.17

Original Text
-------------
[[  first paragraph on page 17: ]]

   PROFILES: Set of non-negative integers, where each integer indicates
   a profile supported by both the compressor and the decompressor.  A
|  profile is identified by a 16-bit value, where the 8 LSB bits
|  indicate the actual profile, and the 8 MSB bits indicate the variant
   of that profile.  The ROHC compressed header format identifies the
|  profile used with only the 8 LSB bits; this means that if multiple
   variants of the same profile are available for a ROHC channel, the
   PROFILES set after negotiation MUST NOT include more than one variant
   of the same profile.  The compressor MUST NOT compress using a
   profile that is not in PROFILES.

Notes
-----
Rationale:  Abuse of language;
  the acronym definitions in Section 2.1 clearly say:
     LSB    Least Significant Bit.
     ...
     MSB    Most Significant Bit.
