No it is not possible to get accurately the one  and zero dimensional 
features
of the domain if you don't describe them explicitly through
the traits class.
You may still run the meshing algorithm
without an explicit description of sharp features.
Then you will get a mesh in which those sharp features
will be rather poorely represented.
