Audio Control schema changes

[Stuart Booth]

Edward,

In your Audio Control schema <waves at Mark> revisions you suggested
changing the playlist edits to send out an event message that just
contains a Playlist.Info message block. This combines several
parameters into the one block:

Playlist.Info
{
Tracks="length of play list"
Index="index of current track"
Shuffle=[On  Off]
Repeat=[Stop  Track  Playlist]
}

So, say I send a playlist shuffle command:

Playlist.Shuffle
{
Shuffle=[On  Off]
}

I would then get back a Playlist.Info event message. But the Event
doesn't actually tell me what specifically has just changed. I'd need
to store the previous state to be able to detect this.

Generally I've preferred to send back the same command as the event
when it is actioned (which makes it dead easy to code too!).

At regular-ish intervals the Playlist.Info should then be sent out
combining all relevant known parameters into one information update.

That's how it works for Class=xAP-Audio.Transport[.Event] so I wonder
if this is an inconsistency?
