The Partial Notification mechanism  requires PA issue NOTIFY
in regular
sequence.

" The PA MUST NOT send a new NOTIFY request that
contains a partial
   notification for the same Request-URI until it has
received a final
   response from the watcher for the previous one or the
previous NOTIFY
   request has timed out. "

What you say is true, but applies specifically to partial
notifications.
Since they send deltas from the previous one they won't work
if
processed out of order.

Some event packages also need such restrictions. But it
isn't a general
restriction.
