Thanks for the explanations but this form does not work.
I had already tried it and the font "Asana-Math" is made
by METAFONT with the following error message (meaning that the
optionnal parameter "[Extension=.otf]" has not been understood)
(/opt/texlive/2019/texmf-local/tex/latex/unicode-math/unicode-math-table.tex)))
kpathsea: Running mktextfm Asana-Math/OT
/opt/texlive/2019/texmf-dist/web2c/mktexnam: Could not map source abbreviation
O for OT.
/opt/texlive/2019/texmf-dist/web2c/mktexnam: Need to update

This version of the command works correctly. I have no idea why
the first form does not work and the second is correct.
I have decided to write a style to solve a problem and to learn
LaTeX3. The learning is harder than I have thought...
Thanks for the help,
Pierre
