Type: Technical
Reported by: Vasiliy Faronov <vfaronov@gmail.com>

Section: 3.2.1

Original Text
     HTTP2-Settings    = token68

Corrected Text
     HTTP2-Settings    = [ token68 ]

An initial SETTINGS frame is explicitly allowed by Section 3.5 to be empty. The payload of an empty SETTINGS frame is an empty sequence of octets, whose base64url encoding is an empty string. Thus, the HTTP2-Settings header field ought to permit an empty string as value. But the ABNF for "token68" does not match an empty string.

This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
