Question: How to add a different NeXus definition repository / How to use non-NIAC NeXus def?

[RonHildebrandt]

Hey there,

I wanted to validate created .nxs files with this tool. But the reference NeXus definitions should be not the ones from the NIAC, but from our FAIRmat-Project: https://github.com/FAIRmat-NFDI/nexus_definitions

From Documentation it seemed to be possible to use as well different tags of the NIAC-NeXus definition, so it should be as well possible to use a different NeXus definition repository?

1. Is this possible?
2. How to do this? I could find a guide for this in the docs.
