The SRv6 base document (approved by the 6man working group) does include additional behavioral requirements for all nodes in an SRv6-enabled domain.

Gyan,

            __ [Gyan]  Spring WG  -??  Because SRv6 uses the same IPv6
            data plan as "Business as Usual" NORMAL IPv6 traffic use
            case of the "internet"  so the an "SRv6 enabled router" that
            has the code that supports SRv6 has the software feature to
            perform the PSP & USP but lets say the packet hits a node
            that does not support SRv6 then the PSP & USP won't occur
            and all the EH headers inserted for SRv6 routing header type
            4 will remain in the packet to the end destination.   How do
            we deal with this issue.



It's not an issue so we do not need to "deal with it".

SRv6 architecture operates just fine over non upgraded (read non SR aware) IPv6 nodes.
