Agenda:

1. Any updates?

   -

   Deyan is finishing a first draft of level 3 ~next week, state of the
   list available at the “Level 3” sheet of the following google sheet, feel
   most welcome to add/comment/change, will remain editable later as well:
   https://docs.google.com/spreadsheets/d/1EsWou1K5nxBdLPvQapdoA9h-s8lg_qjn8fJH64g9izQ/edit?usp=sharing
   -

   The PR for the charter was accepted (it was an update incorporating
   outsiders comments on the charter). Still hope the charter goes up for a
   vote in early January.


2. Sam will finish(?) an update on his ideas for explicit and default
values for intent:  See

SD: Sam discusses updates to his Intent document.

NS: Wants to get rid of the @ operator to search through the children

SD: Added @ignore, @append, @extend

...Matrices and other 2D use the later two -- added to the document

...Discussed examples added to the document for those cases

NS: real example needs context -- are there ()s, ||s, etc around it?

DG: I don’t think array/arrayrow is right as a default -- the presentation
is good enough to be read by AT

BM: I’m not sure the “@” notation is right.

Lots of discussion on defaults for mtable/mtr/mtd and whether they depend
on context

NS: what should happen with special forms like diagonal matrices,
tridiagonal, triangular forms, etc?

SD: moving onto equation arrays -- 2 equations with alignment

SD: also example with linebroken equation across two rows and aligned

Discussion of ‘parsing’ and mrows. Appending, extending, merging, etc.,
discussed.

DG: add some directional ideas: extend-next, extend-right, …

MS: why use eqnarrays vs aligngroups and alignmark.

DC: aligngroup/alignmark never got implemented in browsers and won’t be
implemented



Neil: Request for Comments -- we seem to have a lot of active ideas on the
table markup related to @list and @extend, please read the doc and send
feedback to Sam before the next week.

Neil: Will invite Moritz for next week to discuss microdata solutions as an
alternative to MathML attributes

We meet again next week and the following week and then will take a couple
of weeks off for the holidays.
