Testable? To be tested? 6 MANE and SFM Behavior | 1 #196

If a packet contains an OBU with an OBU extension header then the entire packet is considered associated with the layer identified by the temporal_id and spatial_id combination that are indicated in the extension header. If a packet does not contain any OBU with an OBU extension header, then it is considered to be associated with all operating points.

For discussion.

As written this paragraph is not normative. But there are normative implications on forwarding packets that are "associated with all operating points".

Yes. This could be tested by sending a packet without any OBU with an OBU extension header, and seeing if it is forwarded by the SFU.

The text isn't normative, it is descriptive/definitional.
