I have some questions/suggestions to the Web Apps 1.0 Audio Interface
(http://whatwg.org/specs/web-apps/current-work/#scs-sound) before it
takes off in too many browsers:

1) "The Audio() constructor takes a single argument, a URI (or IRI),
... which returns an Audio object that will, at the completion of the
current script, start loading that URI."

I guess "current script" means "the script statement which created the
Audio object" and not "the entire script".

2) Can you clarify the mechanism to determine if a user agent supports
a particular content type?  Otherwise, as a developer do I just assume
that every browser will support .wav or .mp3 or .ogg or .mid or .... ?
 What about a static method on the Audio interface to query content
types?

I assume there must be something I can do when the load event fires. 
What can I do or check in the load Event to ensure that the content
type is supported by the user agent?

3) I think full URIs should be allowed in the Audio constructor.  Why
must the URI be a relative one?  Is this some crude means of
preventing leaching of bandwidth?  I feel this is artifically
constraining what I should be allowed to do as a developer and as a
service provider.  What if Google wants to start an audio ad program
for websites?  What if I want to start a web service to let web
developers use sounds on my server?

4) The term "repeat count" is misleading.The word "repeat" implies a
re-occurence, so "to repeat once" means to play a total of two times. 
Just globally rename "repeat count" to "play count".  This is more
accurate of what this number actually is (the number of times the
sound will play).

Thanks,
Jeff
