So, 

If the interval start and end point have "seconds" precision, then the
points in this continuum are seconds. 

For the interval 2000-01-01/2000-09-09 the points in the continuum are the
days.

For the interval 2000-01/2000-09 the points in the continuum are the months.

For the interval  2000/2009  the points in the continuum are the years. 

Right?

Here is where I'm confused.  

We have tentatively agreed that we do not need the start and end to have
equal precision. So, for

2000/2009-10

What are the points in the continuum?
