Recently observed about the DFDL Spec 12.3, in a discussion about what can have lengthUnits 'bits'. Note that this also adds that it's not allowed for representation="binary". So we *can* have lengthUnits="bits" for these types when representation="text", we should ensure we still allow that. I think this was not intended. I.e., I think the wording should be clarified to disallow lengthUnits bits regardless of representation for the types where it is currently disallowed.
