Reminder: MathML Full meeting on Thursday (2 hours)

 We meet at: 10am Pacific, 1pm Eastern,* 6pm *GMT*, 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.

This will be another extended 2 hour meeting so we can get through some
important discussions involving "intent". I think this will be our last
extended meeting for a while.

Agenda
1. Announcements/Updates/Progress reports
    Anything that can be closed?
2. Intent issues this week:
   a) Do the # of arguments define a core "intent"?
<https://github.com/w3c/mathml/issues/435> #435
   b) Some specific intent examples
<https://github.com/w3c/mathml/issues/456#top> #456 (turned into function
vs property discussion)
3. Proposed spec changes:
   a)  "_" as a function head needs specification
<https://github.com/w3c/mathml/issues/457#top> #457
   b) Deyan's PR:  IntentName view of literals
<https://github.com/w3c/mathml/pull/459> #459
3. Stepping back: is "intent" usage clear yet? If not, what are the major
questions/disagreements?
