Thanks. This makes sense. I'm wondering if there should be some explanative 
text under "refresh_token". Yet, it doesn't make all that much sense to define 
why something isn't there.  Never-the-less, it just seem like an awkward 
omission after reading it.

I do note, that section 6 (Refreshing an Access Token) does not indicate any 
standard error responses. This seems to be covered by section 5.

The second last paragraph in 6 states: "If valid, the authorization server 
issues an access token response as described in Section 5". 

Maybe that should read: 
"The authorization server issues a response as described in Section 5".  So in 
this case, invalid_grant error would be generated.
