    3131    * the lat, lon and time coordinates must always exist; a vertical coordinate may exist
    32     * coordinates may use missing values, but must do so in a consistent way. Missing coordinate values indicate that the point observation should be skipped.
     32    * auxiliary coordinates may use missing values to indicate that the point observation should be skipped.
    3333    * coordinates are identified with the "coordinates" attribute on the data variables, as specified in Chapter 4 and 5
    3434    * index numbering, if used, is always 0 based

     1242In section 5, first paragraph, change:
     1243
     1244"The dimensions of an auxiliary coordinate variable must be a subset of the dimensions of the variable with which the coordinate is associated (an exception is label coordinates (Section 6.1, “Labels”) which contain a dimension for maximum string length)"

     1246to
     1247
     1248"The dimensions of an auxiliary coordinate variable must be a subset of the dimensions of the variable with which the coordinate is associated (with two exceptions: 1) label coordinates (see Section 6.1, “Labels”) contain a dimension for maximum string length, and 2) the Point Observation indexed and contiguous representations (see Section 9, “Point Observations”) allow special kinds of coordinates which are connected in a differrent way than by the dimension)"
