Mensur signs with only @numbase

It would be useful if <mensur> could display @numbase when there is no @num.

Currently <mensur> can show a @num without a @numbase:

The main issue with using only <code>@num</code> or only <code>@numbase</code> is, that it does not explain how it should be resolved, e.g.:</p> <ul> <li>as 3/2 in a sesquialtera proportion -> needs an implicit denominator</li> <li>as a 3/1 in a tripla proportion (rare but as far as I know possible) -> needs an implicit denominator</li> <li>as modus cum tempore sign -> would be resolved with <code>@tempus</code> and <code>@modus*</code></li> </ul> <p>It definitely makes sense to be able to display a <code>@numbase</code> without <code>@num</code> and vice versa, but I guess in the long run, we need a way to capture the implicit counterpart without displaying it.</p> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/benory"><img src="https://avatars.githubusercontent.com/u/74871483?v=4" />benory</a> commented <strong> 1 year ago</strong> </div> <div class="markdown-body"> <p>Thanks, all, for your help with this!</p> <p>Anna: Ah, the picture that I provided Craig doesn't quite do it justice.
