The CN (common name) names a leaf node in a hierarchy, but provides
no information about the hierarchy that the name belongs to.
The policy protocol provides multiple attributes that can further
narrow down the scope of a CN, but table lookups can only do single
attribute lookup, and then a CN is not sufficient.
