I had a look at the document

  http://www.w3.org/TR/MathML2/PDF-s-MathML-20010221.pdf


In 6.3.2, there is the list:

  Bold

  Italic

  Bold Italic

  Double-struck

  Script

  Bold Script

  Fraktur

  Bold Fraktur

  Sans-serif

  Bold Sans-serif

  Sans-serif Italic

  Sans-serif Bold Italic

  Monospace


In my opinion, there are two entries missing:

  Calligraphic

  Bold Calligraphic


I think that originally, the Calligraphic font of AMS-Fonts was
intended as a substitute for the RSFS like Script in use in European
manuscripts, but they are sufficiently different that they might be
used side by side in a manuscript.


-- Also, I think earlier discussions here and in math-fonts-discuss
said that the Bold Fraktur look awful in print. But if it is in actual
use in mathematical manuscripts, it should be added. I haven't seen it
myself, though. The only use I have seen of Fraktur it is as Lie
algebras, and I do not know why one would want them to be in bold.


-- In addition, I can mention that if one should be very rigorous and
formal with this idea of adding all the math symbols, then one should
add

  Upright

That is, what one now probably will use are the ASCII letters A-Za-z.
Strictly speaking they should have their own mathematical slots, too. I
don't think that this is a very practical suggestion, though, as they
probably will have identical representation with the ASCII letters,
unless one introduces a special math font. So I just mentioned it to
give thought (thinking of math as separate from natural languages).
Strictly speaking, the naming ought to be

  Serif

  Serif Italic

  Serif Bold

  Serif Bold Italic

expect that perhaps "Serif Slanted"<bold> = </bold>"Italic", so that
everywhere the word "Italic" should be replaced by "Slanted" (or
"Oblique"). Etc.
