Hello Authors and all.

Thanks for your patience.

First of all - I think the document describes a useful feature in LISP.
Thank you for writing this doc.

I reviewed this document after reading the ELP definition in RFC8060
section 4.6.
My overall comment is that I was expecting the detailed processing of the
ELP  as  RFC8060 references this document for "details".  Therefore, I find
that the document would be improved if section 5 had  detailed processing
for all cases. I have flagged in the document where some processing should
 be included in different steps.
 Here are major suggestions
- proposed a compromise to make the document clearer on figure 1 and figure
2 and text associated.
- proposed to beef up section 5 need to add processing of L, S, P bits but
more importantly perhaps give the processing with the combinations of bits.

I am attaching the diffs in PDF format as requested in exchanges. If
inconvenient. I can transform the comments in txt.

Let me know if you have any questions

Thanks
Padma
