I also have the same doubt on it;
It May be:
If (SL==0) {
If (NH=SRH) {
then POP current SRH   /**USP**/
     }
Else (NH=41 || 4) {
Then do Decapsulation outer IPx header   /**USD**/
         }

Hello,

For a Single SID:
Endpoint behavior having "End SID with flavors USP&USD"  how to support.
Among USP, USD which must be given priority while processing the packet ?

For both of them precondition is
If (Segments Left == 0) {

As per my understanding  setting  “Single SID” having USP and USD flavor is not appropriate.

Thanks,
