Type: Editorial
Reported by: James Manger <[email-masked]>

Section: 5.1, 4.2.2

Original Text
-------------
expires_in
         RECOMMENDED.  The lifetime in seconds of the access token.  For
         example, the value "3600" denotes ...

Corrected Text
--------------
expires_in
         RECOMMENDED.  The lifetime in seconds of the access token.  For
         example, the value 3600 denotes ...

Notes
-----
The "expires_in" member in JSON must be a numeric value, not a string. Unfortunately quite a few implementations have got this wrong. A likely reason is the quoted value "3600" in the RFC where "expires_in" is defined. The quotes in the text version of the RFC are only an artefact of the marked-up as a protocol value in the RFC production chain.
