The proposed interface does not provide mechanisms for handling
capabilities. With this we refer to the possibility for a user to authorize
other user(s) to perform certain operations on his/her jobs. For example, a
user may want to allow another user to monitor his/her jobs, or to interrupt
and abort jobs and so on. Perhaps this functionality is not strictly related
to job management, but is rather a security issue (which, according to the
draft, is still to be discussed). We may keep it for future discussions..
