The refresh token is bound to the
client it was issued to, and its usage requires client authentication.

Added instead:
The authorization server MUST validate the client credentials, ensure
that the refresh
token was issued to the authenticated client, validate the refresh
token, and
verify that the resource owner's authorization is still valid.
