I understand that it is planned to reintroduce some point specialisations to the model - I think that it would be good to add a specialisation that is a point on the unit sphere, which can be used for RA,Dec etc. Not sure what the best names for the two angles are though so that there is no bias towards a particular usage - but I guess that they could be the same as the equivalent angle names in the full three D spherical point.

@pahjbo
updated the model
c7f3a5b 
These updates address several issues
* ivoa-std#4
* ivoa-std#16
* and the discussion around Quantity where it does not have a "value" defined mean that for practical source generation a cartesian point with a real quantity is needed

IVOA base version 1.1 - potential for better unit.
