Hmmm, from an implementation standpoint, it would be better if the
client could send the last sequence number is has received to the
server, so the server would only have to send events whose sequence
number is > the one provided. E.g., a client sends a server the
"notify-sequence-number" attribute in the Get-Notifications request,
and the server responds only with those events that have a higher
sequence number. This would also reduce the bandwidth used...
Thoughts?
