Dear all,

At the teleconference yesterday, we discussed the Web MIDI API spec, and agreed we'd like to publish as First Public Working Draft next week if Chris found the time to make a few edits - which, as you can see in his e-mail he did.

Publishing at this point will allow us to publicise the work at TPAC, and get more feedback from the public on a spec which is already quite mature. Kudos to the editors.

If there is no objection by Tuesday morning (Boston time) we will assume consensus and will move forward with publication.

Thierry will lead the process for publication, as usual. 
Thierry, since this is a FPWD, can you get the green light for the "webmidi" shortname?

Thank you.

I expect further discussion on this point, but for our FPWD, I wanted to have it this way as I was brainstorming the security and privacy constraints, and I think it may be possible to use sysex as the "needs user permission" switch - that is, to require user permission ONLY in order to send/receive sysex.  I'm not positive this will be enough, but it will be easier to change it back than it would be to break variadic usage later.  ref: Bug 18764.
> 	 I explicitly made timestamps in MIDIMessage allowed to be set to zero, with the semantic of "send now", as per Bug 18760.
> 	 I added IDs to several elements in order to provide forward links, and I expanded some of the IDL constructs to better show the descriptions of individual method parameters or members.  (no substantive changes.)
