I propose leaving things as they are for now. I think the logical place 
would still be where media elements are defined since what we're after 
is essentially something saying that if the "media provider object 
includes information regarding id and label, carry it over to the 
Audio/VideoTrack's created in the media element's Audio/VideoTrackList" 
or something like that.

Similar to what is now said regarding enabled

"If either the media resource or the address of the current media 
resource indicate a particular set of audio/video tracks to enable, or 
if the user agent has information that would facilitate the selection of 
specific audio/video tracks to improve the user's experience, then: if 
this audio track is one of the ones to enable/if this video track is the 
first such video track, then set enable to true, otherwise, set enable 
to false."

How id and label is initiated for MediaStreamTrack's is outlined in
