Scope names can definitely be hierarchicial.  In fact a DN is a legal scope
name - "c=USA;o=Novell;ou=dev.provo.novell".  Note you have to use semicolons
to separate the components, which is legal in LDAP DN syntax.  Commas are 
reserved as scope name separators in scope lists.  This is not an accident.
I though (during the revision of SLPv1 for SLPv2) that one day folks might
want to use DNs to unify SLP and LDAP namespaces.
