Section 10.4.6. says:

   o  When the callback path is down, the server MUST NOT revoke the
      delegation if one of the following occurs:

      *  (...)

      *  The client has not issued a RENEW operation for some period of
         time after the server attempted to recall the delegation.  This
         period of time MUST NOT be less than the value of the
         lease_time attribute.

It should say:

   o  When the callback path is down, the server MUST NOT revoke the
      delegation if one of the following occurs:

      *  (...)

      *  The client has not issued a RENEW operation for some period of
         time after the server attempted to recall the delegation.  This
         period of time MUST be less than the value of the
         lease_time attribute.

Notes:

It does not make sense to revoke the delegation before lease_time period expiration and to not revoke it after.
