Hi Jim,
I leveraged Travis's definition for MediaSettingsRange:  http://dvcs.w3.org/hg/dap/raw-file/tip/media-stream-capture/proposals/SettingsAPI_proposal_v4.html#mediasettingsrange-interface.

I defined a MediaSettingsItem as a sort of counterpart to the MediaSettingsList(http://dvcs.w3.org/hg/dap/raw-file/tip/media-stream-capture/proposals/SettingsAPI_proposal_v4.html#mediasettingslist-interface), but specifically for data types derived from an Enum.  The main difference in my view is that the MediaSettingsItem is essentially a MediaSettingsList with only one item.  My other intention with MediaSettingsItem is to define a single data type that can be both queried for its current setting but also defines a method for setting a new value.

Currently in Travis's doc, querying of the current value setting and the assignment of a new value to that setting result in different attributes.  As an example, in the PictureandVideoSettings interface (http://dvcs.w3.org/hg/dap/raw-file/tip/media-stream-capture/proposals/SettingsAPI_proposal_v4.html#pictureandvideosettings-mix-in-interface), there is a readonly attribute zoom for querying the current zoom setting and there is a writeable attribute of type MediaSettingsRange zooms to allow for setting the zoom value. I think we should discuss this in the group further (maybe during the F2F), because it seems inefficient.

One other minor question:  why does MediaSettingsItem have a read only 'value' attribute, while MediaSettingsRange does not?  Is there any reason that we would want to see the current value for the former but not the latter?

I'd like this to be considered for Picture-specific settings on gUM. The proposal can be found at http://gmandyam.github.com/media-capture/.
