I was assigned as the OPS-DIR reviewer for draft-ietf-netext-pmip-qos-wifi-06. You should treat these comments as any LC comments. In my comments I use datatracker idnits' line numbering.

Short summary:
 The I-D is ready technically but needs another editorial pass.

Operational & management concerns:
  It is a bit unclear to me how the stuff is suppose to work & managed when
  there are STAs with mixed WLAN QoS support, e.g. with VMM and VMM-AC.

Editorial:
  * Throughout the document in many places "section" and "chapter" appear in
    lowercase where they should start with uppercase letter. 
  * Line 144: what is QSTA? Explain and give a reference
  * Section 1.1. Except for "RECOMMENDED" no other RFC2119 terminology is used. 
    Could we change that one in line 711 and then get rid of the Section 1.1
    all together?
  * Section 1.2:
    Line 176: s/Enhanced/Evolved
    Line 182: s/Indicator/identifier
    Line 187: s/Conditioning Spec/Specification
    Then you are missing many many abbreviations from the list. Do a scan for
    missing one and add them.
  * Line 194 & 195: MAC and PHY never expanded nor defined.
  * Line 219: what is PDN?
  * Line 242: s/AIFS.)./AIFS).
  * Line 275: s/PMIP/PMIPv6   (check for other occurrences as well.. there are few).
  * Line 289: PBU/PBA never expanded.
  * Line 330: SIP never expanded or given a reference.
  * Line 428 and onwards: What is QoSx? It is never explained or given a ref.
  * Line 483: UPN is never expanded. Also a reference missing here.
  * Line 520: UPA is never expanded. Also a reference missing here.
  * Line 655: Expand QCI and also give a short explanation what it is.
  * Line 655: s/[[GSMA-/[GSMA-
  * Section 8.2: no reference to SIP RFC.
  * Section 8.2: For WLCP reference you could consider 24.244 instead of 23.402??
