Supermasters' operation clarification

[anon]

oracle backend documentation states:

"A supernotification will be accepted if an entry is found such that the notification came from ip and nameserver appears in an NS record for that zone."

For somebody configuring automatic provisioning of slaves for the first time, it is unclear whether the above paragraph refers to the supermaster or superslave.

The documentation should explicitly state whether this entry is to be found in the superslave's or supermaster's "supemasters" table.
