I've read your message several times and I'm not sure I understand it... 
and what you may mean with open continuous intervals.

A length is a dimension. (...)
A dimension is a number immediately followed by a unit identifier. (...)
A number is either an <integer> or zero or more decimal digits followed 
by a dot (.) followed by one or more decimal digits.

Are you saying that column-width must not be using a real number (eg 
column-width: 12.5px;)?

You say minimum is 1. The spec says greater than 0. Isn't those 



In both these tests, the column-count is 1000 while the width of the 
multi-column container is 192px. Is your message related somehow to 
these 2 tests ?


please put the text "css3-multicol" in the subject and not 
"css-multicol" in the future.
