"Production" ?

[chfremer, 2017/05/10 17:59:40]

Is this about upper-case vs. lower-case? It seems the convention here is to use
lower-case.

[mcasas, 2017/05/10 18:15:44]

My concern is that "production" does not seem to correspond
to any service identifier, which is the rule followed by the 
other services in the vicinity, i.e. something like
"service" : ["interface", "interface"].  
E.g.  "media" says "media": ["media:media"], so, in this case, 
I would expect
"video_capture" : [ "video_capture" ] 
or
"video_capture" : [ "capture" ] 
(the second kind-a points out to more interfaces being
available, e.g. "enumeration").

Done.
