 Hi guys,

 It's clear that convictions run deep on this issue.  It is a lot less
 clear what "this issue" is (so many demonstrative pronouns!).  Here is the
 disputed paragraph, right?

   o If a data variable has two or more scalar coordinate variables, they
 are regarded as though they were all '''independent''' coordinate
 variables with dimensions of size one. If two or more single-valued
 coordinates are not independent, but have related values (for instance,
 time and forecast period, or vertical coordinate and model level number,
 Section 6.2), they should be stored as coordinate or auxiliary coordinate
 variables of the same size one dimension, not as scalar coordinate
 variables.

 Concrete examples that illustrate the undesirable interpretations are
 needed. (At least for this discussion.) The text as it stands is awfully
 dense to serve us well in the standard.  If readers go away scratching
 their heads about the intended meaning, there will be divergent
 interpretations.
