Re: [clue] Participant info/type followup

[Christian Groves <[e-mail]>]

Hello Paul, all,

If we follow the approach that there is a specific indicating of whether 
the participant information is based on an explicit indication then I 
would suggest the following text for the framework:

Clause 7.1.11 Participant information
(Under the 1st paragraph)

The participant information contains an explicit indication of whether 
it relates to a participant contained in the capture, from a 
participants capture device or both. For example a video camera may 
capture an image containing the participant, or a participant may send a 
video capture with a presentation that does not depict the participant.

Something similar would be needed under participant type.

Thoughts?

Regards, Christian
