Hrm - I think that the triangulation has to cover an infinite plane 
(between finite faces and infinite faces).  So you can't have a "hole" 
in the triangle mesh.  (That was my understanding back in CGAL 3.0 at 
least. :-)  You could attach a flag to your face data, allowing you to 
skip marked faces during iteration later.

The newer meshing data types may be better for removing "pars" of a mesh.

cheers
