Hi Robin,
you are absolutely correct. I'm not very familiar with dtschema yet,
so I mostly just did what I know would work, as I didn't know about
"not" or "anyOf" in this context.
However I don't think this patch is going to get a V2 because I may
have found a way to easily get rid of the CRU property altogether,
making this patch sort of obsolete in the very near future.
Thank you for your review nonetheless, I learned some more dtschema
today thanks to it. :)
