Reminder: MathML Full meeting on Thursday

We meet at our standard time on Thursday: 10am Pacific, 1pm Eastern, 7pm
Central European Time.

Note that we are all back in sync wrt setting the clocks back.

The meeting details were sent to the W3C members-only "member-math" mailing
list <https://lists.w3.org/Archives/Member/member-math/2021May/0000.html>
for the group. The regulars for this group should have the meeting details
in their calendars.

Agenda

)

Note: there isn't much detail to what I put in the sheet. I hope I can
write something up on Wednesday for a more coherent discussion (and doing
that might cause me to change a few things). But I promised I would have
for this meeting so I put down some thoughts and some open questions in my
mind.
