Which csg libraries did you found?
The one I found is breplibrary http://breplibrary.sourceforge.net/

It's used in 3dom, a linux modeler.

The header comment in PMViewStructure:

 * Represents the view structure (points, lines, faces) of an object
 *
 * Faces are not implemented yet but are needed later to calculate the view
 * structure of csg objects

I allways planned to add faces to the view structure, that comment is there 
for quite a long time now. Normally the order of the points determin the 
inside and outside, or more mathematically, the direction of the normal 
vector. I think all csg libraries follow this principle.
