How about defining a standard namespace _prefix_ for such additions to
HTML? As far as I've seen, all browsers interpret the namespace prefix as
part of the tag/attribute, such that for MATHML in HTML, you'd use
<math:add>. It'd require the author use the prefix for all relevant tags,
but it should work without changing anything fundamental in UAs that might
break other sites. As far as I'm aware, since namespaces don't exist in
HTML there's nothing particularily "evil" about this.
Now if you'll excuse me, I have some frikkin' lasers to assemble.
