(As an individual contributor and co-author.)

Thanks for extending this, Sue. Maybe it will help the WG to have a reminder about what this document does. 

It’s a revision of RFC 8203. First, here is the rfcdiff vs. RFC 8203: 
http://tools.ietf.org/tools/rfcdiff/rfcdiff.pyht?url1=rfc8203&url2=draft-ietf-idr-rfc8203bis
It is quite short, especially when you skip over the boilerplate and "RFC EDITOR: REMOVE BEFORE PUBLICATION” sections. 

The sole normative change vs. 8203 is the deletion of one sentence:

OLD:
   Length:  this 8-bit field represents the length of the Shutdown
      Communication field in octets.  The length value MUST range from 0
      to 128 inclusive.  When the length value is zero, no Shutdown
      Communication field follows.
NEW:
   Length:  this 8-bit field represents the length of the Shutdown
      Communication field in octets.  When the length value is zero, no
      Shutdown Communication field follows.

The reason for this change is summarized in in Appendix B:

   Feedback from operators based in regions which predominantly use
   multibyte character sets, showed that messages similar in meaning to
   what can be send in other languages in using single-byte encoding,
   failed to fit within the Length constraints as specified by
   [RFC8203].  For example, the phrase: 'Planned work to add switch to
   stack.  Completion time - 30 minutes' has length 65 bytes.  Its
   translation in Russian
   '&#1055;&#1083;&#1072;&#1085;&#1086;&#1074;&#1099;&#1077;
   &#1088;&#1072;&#1073;&#1086;&#1090;&#1099; &#1087;&#1086; &#1076;&#10
   86;&#1073;&#1072;&#1074;&#1083;&#1077;&#1085;&#1080;&#1102; &#1082;&#
   1086;&#1084;&#1084;&#1091;&#1090;&#1072;&#1090;&#1086;&#1088;&#1072;&
   #1074;
   &#1089;&#1090;&#1077;&#1082;.&#1042;&#1088;&#1077;&#1084;&#1103; &#10
   79;&#1072;&#1074;&#1077;&#1088;&#1096;&#1077;&#1085;&#1080;&#1103; -
   30&#1084;&#1080;&#1085;&#1091;&#1090;' (See PDF for non-ASCII
   character string) has length 139 bytes.

Now you do not need to actually go read the draft in order to know everything you need to respond to the WGLC. :-)

Thanks,

—John
