Capture Properties

I'm implementing support for camera's I use into opencv itself. Now, it seems that there are lots more properties accessible than is apparent in the documentation. Here's a list if properties I've found (with the obvious ones removed).

CV_CAP_PROP_FORMAT: Pixel format, I suppose.
CV_CAP_PROP_MODE: Capture mode. fixed framerate or external triggers perhaps?
CV_CAP_PROP_CONVERT_RGB: Convert any requested pixel format to RGB24?
CV_CAP_PROP_MONOCROME: Convert to monochrome. Does this take precedence over CV_CAP_PROP_CONVERT_RGB?
CV_CAP_PROP_TEMPERATURE: Colour temperature?

Can someone briefly explain what the expected "behaviour" is for these values?
