5.2.3.18.  Preferred Key Server

   (String)

   This is a URI of a key server that the key holder prefers be used for
   updates.  Note that keys with multiple User IDs can have a preferred
   key server for each User ID.  Note also that since this is a URI, the
   key server can actually be a copy of the key retrieved by ftp, http,
   finger, etc.
