[Nexus] Using NXxas for XMCD experiments

[Fernan Saiz]

Dear Nexus community,

I was wondering if any member here has been used NXxas 
<https://manual.nexusformat.org/classes/applications/NXxas.html> for 
XMCD experiments given that XMCD can be assumed to be the difference of 
two XAS spectra obtained under plus and minus magnetic fields and 
divided their sum. The reason behind my question is that I see much 
simpler to add the information about the magnetic field by filling out 
e.g. *magnetic_field *in the NXsamplerather than coming up with a new 
application definition. The former option can be also complemented by 
providing information about the magnet (e.g. NXquadrupole_magnet).

Any thoughts would be welcomed.

Sincerely,
