DC: 'pdf.js' (used in Firefox) supports tagging but not MathML. They are
waiting on the sanitizer to handle MathML.

Issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1937438

3. #526: Add mathvariants isolated, roundhand, and chancery
<https://github.com/w3c/mathml/issues/536>

Consensus: don't add to spec, but ok to add to polyfill.

There is a problem that the fonts don't (or didn't at some point in time)
use the font variant for these.

Action: DC to investigate the current status of what the fonts that have
these characters do (private area? use the variant selector?, ...)

4. #449: Intent Properties: ordering & references
<https://github.com/w3c/mathml/issues/449>

A lot of discussion about how references and properties should be
interpreted. The bottom line is "it's complicated". One option would be to
disallow properties on references and therefore remove the complication. We
should look to see how limiting this is.

bDC will look at the intent examples that he wrote. BM has an algorithm in
mind that he will write down.

Action:: BM to specify his algorithm in the issue

Action: DC to look at intent examples and see what is forbidden by
eliminating propties on references. Others to think about examples that
might be limited.
