[Markus Demleitner]

Hi List,

and apologies for receiving two mails -- I wanted to keep the two
threads separate.

No -- this was my attempt to say why 'log' and log should be
different.  And why one might give an error and the other not.

That in VOUnit, it is the unquoted one that should work and the
quoted one that should error out... well, VOUnits is not python.
