Comment (by stevehankin):

 The idea of an attribute "modulo=[length]" has been proposed in trac email
 discussions on a number of times and is badly needed.  The fact is that
 users have been utilizing such attributes for years (pre-dating CF) ...
 just have never found the energy to converge on a CF encoding.  Here's an
 example in the documentation for the Ferret program:
 http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/Grids-
 Regions/REGIONS#_VPINDEXENTRY_731

 However, the use of the modulo attribute does not negate the requirement
 that the numerical encoding of the axis be monotonic.  It merely informs
 the application reading the coordinates that (for modulo=360) a coordinate
 of -180 is the same position as a coordinate of 540.
