over progress on issues from last week

NS: MathML entities are based on https://w3c.github.io/xml-entities/

NS: Should we keep both the compressed view and sortable view?

BM: Seems machine readable. We should link to the machine-readable file

NS: consensus

   - compressed display of authors and WG members
   <https://github.com/w3c/mathml/pull/277>
   we didn't seem to come to a conclusion last week -- hopefully no
   objections and we can do the merge

NS: wants to shrink this down.

DC: agreed.

DC: will reformat to shrink the text. The extra text becomes a tooltip.

NS: consensus agreement to shrink

   - delete glossary for issue #291 <https://github.com/w3c/mathml/pull/292>
   most discussion in the issue at: issue 291
   <https://github.com/w3c/mathml/issues/291>

dc: Wanted to drop it from the normative specification.

SD: wants to have an informative document where this information can be
stored.

NS: Consensus to remove from normative spec and move to informative one

   - delete macros and mode attributes, reference legacy schema
   <https://github.com/w3c/mathml/pull/293>

NS: this is really about whether we continue to talk about previously
deprecated features.

DC: wants to remove them. There is a legacy MathML schema that will include
them.

NS: If you deprecate something, it should eventually disappear. If you
deprecate something in spec 4, it should disappear in spec 5, except for an
entry in the spec 5 change log in the appendices.

DG: is enthusiastic about this.

DC: If a deprecated thing is still used after 20 years, it should become
part of the standard, perhaps in the full specification.

DC: perhaps we must consider each element separately.

NS and DG: full math and very very thick math space still exists. This has
been deprecated. But it is still in core.

NS: consensus

   - Make the sample presentation of Strict Content use intent
   <https://github.com/w3c/mathml/issues/284>

There was not time to consider this issue in this meeting.

   - From core: Stable and compact operator dictionary
   <https://github.com/w3c/mathml-core/issues/104>

NS: reviewed the situation. Fred does not want to keep changing the
operator dictionary as often as we have been changing it.

DC: Eventually we should freeze the dictionary when the spec is near
finished.

NS: Looked at z-notation colon and agreed with David -- relational op
spacing is what is used in their spec.

DC: other issues seem to be dealt with (therefore/because), vertical bar,
etc.

Fred can implement his plan.

NS: Consensus. With changes, add a note of agreement to the Core issue.

   - For Next Week:

SD: wants to consider his changes in section 4.6.
https://github.com/w3c/mathml/issues/278

SD's local branch brings together the rewrite rules into 4.6, but still
needs editorial fixes around the edges. https://samdooley.github.io/mathml/

SD: I plan to keep working on this and get it ready for a pull request.
Comments welcome.

SN: wants to talk about how accessibility is handled in other
specifications. issue 282.

SN: What is the best method to deal with issues about accessibility in HTML?

SN: Other specs use AREA, and he does not think this would be useful for
MathML.

SN, the Epub spec has accessibility guidelines.

NS: will be working on chapter 3.

*Europe switches to summer time on March 27. The U.S. switched to daylight
savings time on March 13. For those outside the US, next week's meeting
will be one hour earlier than normal.*
