At this point I'm mainly interested in using this to represent
Echelle spectra as envisaged in
https://github.com/ivoa-std/SpectrumDM/issues/2#issuecomment-1189166132

Do you already see how one would do that?  In particular, am I
already doing what you intend (modulo some utypes and UCDs) in my
pseudo-SDM Echelle spectra, e.g.,
<http://dc.zah.uni-heidelberg.de/getproduct/flashheros/data_raw/ca98/blue/n0393.mt>?

If not, and structural changes are required: What would those be?

Thanks,

          Markus
