This is a global directory service, where names are assigned within a
 naming hierarchy.  The entire name, including all of its hierarchical
 levels, makes up the "full name".  One possible format for a full name
 is:

   <ns>:.<dir>.<dir>.<node-name>

 Where:

   <ns>:        is the name of the namespace for this naming hierarchy.
                For example, this could represent the organization.

   .<dir>       is some directory name used to break the namespace down
                into smaller, more manageable segments.  For example,
                this could represent an organization, an organizational
                unit, or a location within an organization.  There can
                be as many levels of directory as needed.

   .<node-name> is the terminating name for some node.

 The actual name structure can be defined to suit the name usage of
 the organization.  If the above structure is used, an example of a
 complete full name might be:

   MYCO:.TOPEKA.MYNODE
