(I think a Line of 0 lenght must be invalid)

However is true that a line is define from almost 2 point everywhere 
they are, (but can they be all in the same position ?)
And also is even true that a line is dimensional different from a 
multi-point.

A point is 0-dim, a line is 1-dim (a poly is 2-dim)

A line defined with only 2 point on the same coordinate, how can be a 
1-dim geometry ?
