Tobie, thanks for nicely summarizing what I was trying to say :)

The spec clearly serves the former scenario, because the accept (+ the potential live boolean) tackle the latter. I added the following note to clarify this, feel free to suggest better wording, extend it with more concrete examples etc.:


A future version of this specification may define other keywords.


In line with this clarification, I renamed the generic term "A still image capture device" to a specific term "A camera" in the "Capture control type" column for the "camera" keyword.
