Scalar coordinate value seems much more computable. I'm assuming if the coordinate value is absent, the default applies.

Hi Alison,

John's response got buried in my 'todo' pile. His 'flexible' definition almost works for me, but I would prefer to take 2um (the definition of field taxonomists) as the default, giving a definition like:

'Picophytoplankton are the smallest size class of phytoplankton with a maximum size of 2um for observational data and some models. Other models may specify the upper limit elsewhere in the range 2-5 um, in which case the actual upper limit used should be specified.'

Whether this specification should be done through the long name or a scalar co-ordinate variable as John suggests is something I'm not sure about. Anybody any preferences?

Cheers, Roy.
