IVOA Simple Line Access Protocol v0.2

[Markus Dolensky]

Hi Doug,

Can't see anything wrong with it. As discussed off-line we may have also cases 
where we whish to express an exclusion of range(s) when collapsing cubes and 
that seems to work just fine as in this example:

  "smaller than 1 or between 3 and 5 or bigger than 7" would be become

param = :1,3:5,7:

(right?)

Cheers,
Markus
