that is defined in chapter 6:
   http://www.w3.org/TR/2009/WD-MathML3-20090924/chapter6.html#encoding-names
should it be repeated in our appendix hence in this registration then?

I can change this.
Wouldn't it be wishable to reference draft-murata-kohn-lilley-xml-03  
instead?
Does anyone know when it'd be authoritative.

Can you suggest something?
MathML entities exchanged on the web have the same risks as any  
document that could contain relative references. Is this the kind of  
sentence that could be there?

misplaced like it's wrongly formulated? Formatted?

thanks, will do.

this appears clear

Should there be an email? (there's one three lines above)
Should there be a group? That is easy to add.
