Correct, I missed that as they are using different (yet equivalent) syntax.
So this range is defined for BG, DE, NL. This is still very much the
exception rather than the norm.
I maintain my opinion that these ranges should be removed on the basis
that it is very low power and poses a risk in the presence of
