--------------------------------------
Status: Verified
Type: Technical

Reported by: Klaus Hartke <hartke@tzi.org>
Date Reported: 2017-02-22
Verified by: Francesca Palombini (IESG)

Section: 5.10.7

Original Text
-------------
If any
of these reserved option numbers occurs in addition to Location-Path
and/or Location-Query and are not supported, then a 4.02 (Bad Option)
error MUST be returned.

Corrected Text
--------------
If any
of these reserved option numbers occurs in addition to Location-Path
and/or Location-Query and are not supported, then the response MUST
be rejected (Sections 4.2 and 4.3).

Notes
-----
The Location-* options are used in responses. A client cannot return a 4.02 (Bad Option) response in reply to a response. The correct behavior is to reject the response.
