<p>Approvers notify the user that new channels have been created,
and allow the user to accept or reject those channels.</p>
<p>They can also select which channel handler will be used for the
channel, for instance by offering the user a list of possible
handlers rather than just an accept/reject choice.</p>
<p>However, the Channel Dispatcher must be able to prioritize
possible handlers on its own using some reasonable heuristic,
probably based on user configuration.</p>
<p>It is possible (and useful) to have an approver and
a channel handler in the same process; this is particularly useful
if a channel handler wants to claim responsibility for particular
channels itself.</p>
<p>All approvers are notified simultaneously. For instance, in a
desktop system, there might be one approver that displays a
notification-area icon, one that is part of a contact list
window and highlights contacts there, and one that is part
of a full-screen media player.</p>
<p>Any approver can approve the handling of a channel with a
particular channel handler. Approvers can also request that the
channel is rejected. The first approver to reply gets its decision
acted on; any other approvers that reply at the same time will
get a D-Bus error, indicating that the channel has already been
dealt with.</p>
<p>Approvers should usually prompt the user and ask for
confirmation, rather than dispatching the channel to a handler
straight away.</p>

<p>A specification of the channels in which this approver is

same way as ObserverChannelFilter, but the group has the same

in which the approver has registered an interest is created,

operations already exist.</p>
<p>The channel dispatcher SHOULD call this method on all approvers
at the same time. If no approvers return from this method
successfully (including situations where there are no matching
approvers at all), the channel dispatcher SHOULD consider this
to be an error, and recover by dispatching the channel to the
most preferred handler.</p>
<tp:rationale>
Processes that aren't approvers shouldn't be making connections
anyway - there should always be at least one approver running.
