This is not something that a user of rialto-gstreamer needs to be concerned about (it is done automatically). This API is to query if a specified set of properties are supported on the RialtoServer. This enables RialtoGstreamer to determine the set of properties to present, and support, for the clientuser of rialto-gstreamer. This will happen upon creation of a pipeline (when a sink is created).
