1. Definition
The focused status data obtained by interpreting the individual and collective behaviour of Participants in the Real Environment Descriptors, per the current Cue Point as required by the Action Descriptor Generation AIM to service the current cue point.
2. Functional Requirements
RE Participant Status includes only those RE Participant Descriptors that are relevant per the current Cue Point Conditions and Actions for hand over to the Action Descriptor Generation AIM as well as collective behaviour of Participants relevant to current Cue Point Conditions and Actions.
