I think we're over the edge into what gets returned by getCapabilities()

The labels are intended to be whatever makes sense for that OS/hardware 
platform. Most of the time, for browsers that are not integrated into 
the platform, the browser will have no control over the strings, so 
can't provide translations; the OS may have facilities for relabeling 
devices, but I think that's out of scope for this API.

I thought I'd keep the "group" together with the "id" attribute as 
"available before being granted permissions", but don't feel strongly 
about that.
