The IVOA Units document v1.0, Derriere and Gray 2014,
http://www.ivoa.net/documents/VOUnits/,
has this to say in section 1.4:

   This Recommendation does not prescribe what units data providers
   employ, except to the extent that we avoid giving a standard
   interpretation for a unit in some cases (for example we do not
   acknowledge the degree celsius or the century as units). Since we
   do not forbid ‘unrecognised’ units, this need not restrict data
   providers.
