- PPPoE and IPoE have accepted meanings for broadband network access.
This draft has nothing to do with IPoE.
       It is true that PPPoE can be used to carry a variety of
protocols, including IPv4 and IPv6. This is exactly the same for RFC
2516 and this draft.
       The protocol being carried by PPPoE is specified by the
PROTOCOL_ID field whose assigned values appear in
https://www.iana.org/assignments/ppp-numbers/ppp-numbers.xhtml#ppp-numbers-2
 You may be confused because in this draft the PROTOCOL_ID field is
explicitly shown in the figure at the top of page 5 while in RFC 2516
it just says "payload" but if you read Section 6 of RFC 2516, you will
see that "The PPPoE payload contains a PPP frame.  The frame begins
with the PPP Protocol-ID." Thus, both RFC 2516 and this draft have
exactly the same Protocol-ID field in exactly the same place in the
header although with different capitalization and punctuation.

- The draft does not specify "a new encapsulation format structure".
It uses the existing "encapsulation format structure" for PPPoE data
from RFC 2516, which is why it references RFC 2516 and increments the
version number, with the relatively minor change that it redefines the
contents of the CODE field which is unused in RFC 2516 for data
packets.

When an externally derived specification is published by the IETF, it is normally published as informational.

This draft does propose identifying IPv4/IPv6 datagram to 5G equipments. Therefore, I still think the draft should propose for standard, what do you reply?

As I explained above, this draft and RFC 2516 have exactly the same
"field-format" for identifying the protocol type of the further
content of PPPoE data frame payloads and both can carry a variety of
protocols including IPv4 and IPv6. I have already explained why it
should be Informational, not Standards Track.
