As I read the spec, no, it is not. From the beginning of section 5, paragraph 3:
"The value of the coordinates attribute is a blank separated list of the names of auxiliary coordinate variables. There is no restriction on the order in which the auxiliary coordinate variables appear in the coordinates attribute string."
In addition, some of the auxiliary coordinate variables may not correspond to a variable dimension at all. If want to specify that your 2-D surface temperature data is taken at a reference height of 2 meters, for example, you define a scalar coordinate variable to store the value '2' and include that variable name in the coordinates attribute. (See 5.7 for an example.)
