Added new section and changed all duplicate definitions of 'scope' to reference 
it:

3.3.  Access Token Scope

   The authorization and token endpoints allow the client to specify the
   scope of the access request using the "scope" request parameter.  In
   turn, the authorization server uses the "scope" response parameter to
   inform the client of the scope of the access token issued.

   The value of the scope parameter is expressed as a list of space-
   delimited, case sensitive strings.  The strings are defined by the
   authorization server.  If the value contains multiple space-delimited
   strings, their order does not matter, and each string adds an
   additional access range to the requested scope.

   The authorization server MAY fully or partially ignore the scope
   requested by the client based on the authorization server policy or
   the resource owner's instructions.  If the issued access token scope
   is different from the one requested by the client, the authorization
   server SHOULD include the "scope" response parameter to inform the
   client of the actual scope granted.
