    8       The previous section contained several examples in which measurements from scattered sites were grouped using a single dimension. Coordinates of the site locations can be provided using auxiliary coordinate variables, but it is often desirable to identify measurement sites by name, or some other unique string. 
     8      The previous section contained several examples in which measurements from scattered sites were grouped using a single dimension. Coordinates of the site locations can be provided using auxiliary coordinate variables, but it is often desirable to identify measurement sites by name, or some other unique string. Other purposes for string identifiers are also described in <xref linkend="geographic-regions"/>, and <xref linkend="statistics-applying-portions"/>.

    11       The list of string identifiers plays an analogous role to a coordinate variable, hence we have chosen to use the <varname>coordinates</varname> attribute to provide the name of the variable that contains the string array. An application processing the variables listed in the <varname>coordinates</varname> attribute can recognize a labeled axis by checking whether or not a given variable contains character data.

An application processing the variables listed in the <varname>coordinates</varname> attribute can recognize a labeled axis by checking whether or not a given variable contains character data. If a character variable has only one dimension (the length of the string), it is regarded as a string-valued scalar coordinate variable, analogous to a numeric scalar coordinate variable (see <xref linkend="coordinate-system"/>.)
