If the XML Core Working Group disagrees with my reading of the Charmod
Recommendation, please discuss this matter with the I18N Core Working
Group such that corrections will be published that clearly invalidate my
interpretation.

It's b), http://lists.w3.org/Archives/Public/www-style/2005May/0022.html

But this doesn't matter here, I want XLink 1.1 simply be defined such
that it conforms with C014 and the rest of the Character Model. Conforms
to my interpretation of it, if you must.
