Comment (by edward.campbell):

 Hello,

 I strongly disagree with your proposed change. You claim that this is a
 clarification and not a material change. I do not agree with this.
 Specifically, you wish to append a section stating that if a data variable
 has two or more scalars coordinate variables those scalar coordinate
 variables are independent. This is not currently the case - they may be
 independent, they may not be - the conventions make no assertion either
 way. If the dimensions are not specified one cannot currently infer
 independence. Put another way, without a dimension (a direction if you
 like) these are true scalars as opposed to unit vectors. Your proposed
 change will impose a single interpretation of existing data where a single
 interpretation does not currently exist. That in my view constitutes a
 material change.

 Ed
