<p>Now, I have a hard time coming up with examples of "presentation

digits and are *not* related to some "typographical convention".</p>
<p>The problem with <sup> seems to be more in the fact that
there's more than one convention that might apply.</p>

When HTML introduced the `b`/`strong` and `i`/`em`
distinctions, it should also have added
presentational/semantic pairs<br>
<br>
- `sup`/`exp` (exponent) or `pow` (power) and<br>
- `sub`/`idx`, `ind` (index) or `base`.<br>
<br>
I don’t think the WHATWG or W3C would be interested in
adding them now.<br>
