You nailed it, Mike. H.5 is the intended illustration where "A9.2.3.2"
is referenced. Thanks for pointing out the error.

Hi,
I'm working on understanding how to properly express nominal and
precise locations for timeSeriesProfile data from an oceanographic
mooring. Here is the text from section 9.5 at
http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cf-conventions.html#coordinates-metadata:
CF Discrete Geometries provides a mechanism to encode both the
nominal and the precise positions, while retaining the semantics
of the idealized feature type. Only the set of coordinates which
are regarded as the nominal (default or preferred) positions
should be indicated by the attribute axis, which should be
assigned string values to indicate the orientations of the axes
(X, Y, Z, or T). See example A9.2.3.2. Auxiliary coordinate
variables containing the nominal and the precise positions should
be listed in the relevant coordinates attributes of data
variables. In orthogonal representations the nominal positions
could be coordinate variables, which do not need to be listed in
the coordinates attribute, rather than auxiliary coordinate variables.
I can't find example "A9.2.3.2", but did find example H.5 which looks
to be the correct one. Is this just a simple typo in the above text?
