Hello,
I think we can still take editorial fixes. I just have a few questions..

So would the correct fix be to remove
   ; these attributes are said to be in the "per-element-type namespace partition"
from the paragraph, or did you want to replace that with something else?

Ok, I've updated the SVG links to match and updated the MathML reference
to MathML3.

Ok, I will update these references. They should be pointing to 2.1. :)
