Re: WGLC of draft-ietf-xmpp-6122bis-11

I've finished reviewing draft-ietf-xmpp-6122bis-11.  I mostly think
this document is ready to be published.  I think it deals with the
internationalization issues at hand as well as can be expected.

However, in 3.2. Domainpart, I wonder about the following:

  4.  So-called "additional mappings" MAY be applied to the domainpart,
       such as those defined in [I-D.ietf-precis-mappings] or [RFC5895].

As far as I can tell, just about all of the suggested mappings from
RFC5895 are already required here.  But for any that are not, I worry
about the potential for interoperability problems if say two servers
communicating with each other apply different mappings.  It might be
best to strike this bullet from the list.

Less concerning to me is in 3.3. Localpart:

   2.  So-called "additional mappings" MAY be applied, such as those
       defined in [I-D.ietf-precis-mappings].

I think there is less concern about interoperability problems here,
but I wonder if it is of any real utility.

The similar language in 3.4. Resourcepart is not concerning to me at
all; there are some cases where additional mappings are desirable
(e.g., MUC nicknames), and I think the language makes it clear that
anything beyond "it's opaque" is to be approached with care.


Thoughts?
