    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.
