That -isn't- explicitly stated, it is saying that they should be sent
to mark the start or end of accounting - that's not tied to only a
startup, a reboot or a shutdown. The spec uses those as examples of
when it is appropriate. It doesn't say they are the only times that
they can be sent.

The spec does not prohibit WLAN vendors scoping the start or end of
accounting with a Calling-Station-Id so some seem to have taken that
liberty, and send these on a per-BSS basis and not on a per-NAS basis.

I agree with you that adding a new Acct-Status-Type would be more
appropriate and mandating that Accounting-On and Accounting-Off be
sent only on a per-NAS basis would be the best way forward.

Yes, we could do with a new spec that cleans this up! :)
