Hi Andy,
Thanks a lot for your objective and fair comments. 
Best regards,Xiaohu

The following URL is a diff between draft-farrel-mpls-sfc-04 and draft-farrel-mpls-sfc-05, when section 6 was updated to change Segment Routing to “Label Stacking”. (Note that the only changes from draft-farrel-mpls-sfc-05 to draft-ietf-mpls-sfc-00 were the name and date change).
https://tools.ietf.org/rfcdiff?url2=draft-farrel-mpls-sfc-05.txt

If you examine the changes to section 6, it’s pretty clear (at least to me) that the changes are really just cosmetic in nature, such as removing a reference to draft-ietf-spring-segment-routing and changing a few terms here and there. 
That, combined with the fact that the MPLS WG had never discussed “Label Stacking” in a draft (never mind an RFC) prior to the introduction of Segment Routing leaves me to conclude that section 6 really does need to be removed in order to comply with the WG concerns about -04 and earlier revisions of draft-farrel.
Thanks,Andy
