Formatting of values (as italics) vs units (as upright) about bipm-si-brochure HOT 4 CLOSED

This is what we hoped to have the Ascii-based units formatting language address, but I guess we're not going to wait for that.

Your requirement is backwards: it is the upright, not the italics, which is the exception. I doubt this can be done directly at all, and what will be necessary is some ad hoc postprocessing, where formatting is passed through in the AsciiMath parse, and then processed before moving on to MathML; something like stem:[5 !m^{-2}], where we agree that ! makes the following character upright.

Proccessing Asciidoctor markup is a non-starter. Treating units as text in AsciiMath is also a non-starter. That is not how you're going to get the markup you want.

Will need to experiment with this.

Recall: by default in MathML, two-character variables are upright, single-character variables are italic.

Asciimath gem decomposes two-character variables into single-character variables. So everything turns into italics. The real solution to that is going to have to be true units markup. But before we get there:

Asciimath applies font shifts to its arguments: so

stem:[v bb(ms)^{-2}]

renders as:

<math xmlns="http://www.w3.org/1998/Math/MathML">
<mi>v</mi>
<msup><mrow>
<mstyle mathvariant="bold"><mrow><mi>m</mi><mi>s</mi></mrow></mstyle>
</mrow><mrow><mrow><mo>−</mo><mn>2</mn></mrow></mrow></msup>
</math>

That won't be the desired <mi mathvariant="bold">m</mi>, but if we want proper semantic markup, we should be using a real units markup scheme anyway.

So we could address this for now, at least for rendering, by changing the markup to stem:[v rm(ms)^{-2}]. The problem with that is, rm is not supported by most Asciimath implementations. Am requesting it to be implemented in Asciimath gem.

I applied rm(...) syntax to all units in stem expressions of BIPM SI Brochure EN/FR (#56 ).

@Intelligent2013, unassigning you, there is nothing for you to do.

There is a task to do units in UnitsML properly: metanorma/metanorma-bipm#3 . This interim solution is working, so closing ticket.
