There was quite a big discussion about this a few months back, the
results of which are summarized by this posting from Jonathan Gregory:

believe this was agreed to (I thought there was a trac ticket but can't
seem to find it now --?)

My understanding is that it is correct (but optional) to define it for
'xc', whereas it would be incorrect to define it for 'lon' in your example.
