Well, that would be the ideal way.  But really, you could also just
file an issue with ±standard-suitable text and leave it to the editor
to place it if you are unsure.

If you don't want to figure out the FITS part, I think the WG can
help out.

IIRC you also use SpectrumDM utypes to annotate spectral/flux columns
coming out of in-database spectra.  I think that is a very good
thing, too, and the SpectrumDM update would be a good opportunity to
add a (non-normative, for now) appendix saying something about this
kind of usage.  I'd volunteer to write this if other people also
think that's a worthwhile thing.

Thanks,
