| Hi.
How about this?
In cases where a variable containing coordinate data does not conform to the definition of a coordinate variable, it is identified by naming it in a coordinates attribute associated with one or more data variables.
Grace and peace,

Dear all,
In the Overview section 1.3 of the CF standards, the following sentence appears:
" In cases where coordinate variables are not applicable, the variables containing coordinate data are identified by the coordinates attribute."
This implies to me that "where coordinate variables *are* applicable, one should not use the coordinates attribute to identify them", which is incorrect, since near the beginning of chapter 5 we state " Note that it is permissible, but optional, to list coordinate variables as well as auxiliary coordinate variables in the coordinates attribute. "
If anyone else thinks the sentence in the overview section is misleading, perhaps we should submit a "defect" changing that sentence to:
"The second option is to include the coordinates attribute, which identifies variables which are not necessarily "coordinate variables" in the NUG-defined sense, but which in fact are used to store coordinates."
What do you think?
cheers,
Karl
