Hello Dan,

Thanks for the nice example. I think there is an extra case you could
include. From #104:

  "If a string-valued auxiliary coordinate variable has only one
   dimension (the maximum length of the string), it is a string-valued
   scalar coordinate variable"

Adding that to your example (dimension maxlen, variable u):

 dimensions:
   x = 180;
   y = 290;
   p = 1;
   n = 5;
   maxlen = 256;
 
 variables:
   float d(y, x, p, n);
     d: coordinates = "lat lon h s a z t u";
 
   float x(x); # coordinate variable
   float y(y); # coordinate variable
   float p(p); # size 1 coordinate variable
 
   float lat(y, x); # auxiliary coordinate variable
   float lon(y, x); # auxiliary coordinate variable
   float h(p); # size 1 auxiliary coordinate variable
   char s(n); # string-valued auxiliary coordinate variable
   char a(p); # size 1 string-valued auxiliary coordinate variable
 
   float z; # numeric scalar coordinate variable
   char t; # string-valued scalar coordinate variable
   char u(maxlen); # string-valued scalar coordinate variable

All the best,

David
