NS: questioned acceptance of ordinal mark intent.

Ordinal mark is out

day-period is out

Action PL: open an issue to discuss whether constants such as r, d, Z and
remove from core list for the moment.

Remove translates-to -- same as maps-to

Discussion on Translation, Rotation, Reflection -- common concept in grade
school geometry but the notation is unclear as to how common it is.

DG: this used be what we called level 2, but now merged with open.

Agreed: leave them out for now.

Add:

   - m(angle sign) angle-measure
   - binomial-coefficient
   - magnitude
   - add vector property on table (1 row/column or mrow)
   - add example for vector/matrix concept
   - unit-vector (left off here)

NS: I'll try and go through more of the list and add things I think are
uncontroversial.
