Reminder: MathML intent meeting on Thursday

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

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:
1. Announcements/updates
    (upcoming meetings/holidays)
2. Deyan is stepping up to the plate this week with his version of the
intent proposal
3. Discussion on intent and how to move forward (pick one, resolve
differences, ...)

As a reminder, here is what has been discussed:
Bruce's material:
Proposal: https://mathml-refresh.github.io/discussion-papers/semantics-mini
I think Deyan's demo page (with some options selected) mostly reflects the
proposal:
https://dginev.github.io/tiny-mathml-a11y-demo/

Sam's material:
Proposal: https://samdooley.github.io/mathml-docs/intent2cmml/intent.html
Demo: https://samdooley.github.io/mathml-docs/intent2cmml/demo.html
(updates on paste)
