Hi Gunter,

Thank you so much for the editorial rewrites you suggested. I adopted all o=
f them.
Thank you so much for the checklist/guidelines you provided for the securit=
y and operational considerations. They're always my headaches, but now I wa=
s able to check against the guidelines and added an operational considerati=
ons section.

I have uploaded the -12 revision.

Hi Jeffrey and BIER WG,

Please find here a shepherding AD review of draft-ietf-bier-php-11

Many thanks to Xiao Min for the excellent Shepherd write-up. It was great t=
o see that the work has been validated with the MPLS Working Group. I also =
noted from the email archive that Loa provided some valuable feedback, whic=
h has been thoughtfully incorporated.

When running idnits, a few messages appeared, likely due to the references =
being slightly outdated over time. You can view the idnits report here: htt=
ps://urldefense.com/v3/+AF8AXw-https://author-tools.ietf.org/api/idnits?url=

The document currently lacks an operational considerations/implication sect=
ion. To assist with this, I've added some initial thoughts on the operation=
al aspects associated with PHP operation at the very end of this AD review =
for inspiration and to discuss if they apply to the BIER use-case.

The security section is somewhat brief. I've included some ideas to help ex=
pand on the security considerations related to PHP and its application with=
in BIER. Not all the suggested observations will apply strongly for this BI=
ER use case.

While the document effectively outlines the operational procedures, it coul=
d benefit from some grammatical enhancements to improve clarity. Given that=
 this draft is concise, I thought it would be more convenient to propose th=
e revised text section by section rather than suggesting edits paragraph by=
 paragraph. This approach should make it easier to incorporate the suggesti=
ons into the XML.
