The node to be exported can be specified using one of its NETs (or
 NSAPs), or its Phase IV address.

 An NET is an NSAP address value with an N-Sel value of "00" (indicating
 that it is independent of the type of transport service in use on the
 node).  If you specify an NSAP instead of an NET, it is converted to an
 NET before it is used.

   DNA format:  <afi>:<idi>:<predsp>-<locarea>:<nodeid>:00
   OSI format:  <afi><idi>+<predsp><locarea><nodeid>00

 Examples of NETs might be:

   DNA format:  39:840:0001:AA-00-04-00-05-04:00
   OSI format:  39840+0001AA000400050400

 If the node has a Phase IV address, that can be used instead of an NET.

   Format:      <area>.<nodeid>
                <area>.<nodeid>+<prefix>

 This is internally converted to an NET, using the Phase IV prefix value.
 The Phase IV prefix value can be specified with the Phase IV address,
 or set as a default using the preferences form.

 Examples of a Phase IV address might be:

   1.5                                Uses the default Phase IV prefix
   1.5+39:840                         Uses an explicit Phase IV prefix

 Wildcards are allowed in the NET or Phase IV address using an asterisk.
 The wildcard character must replace either the node id, or the local
 area and the node id.  For an NET containing a wildcard, do not specify
 an N-Sel value.

   39:840:0001:*   (or 39840+0001*)   Wildcard the node id
   39:840:*        (or 39840+*)       Wildcard the local area and node id

   1.*                                Wildcard the node id
   *.*                                Wildcard the area and node id
