The APPN DLUR Architecture Reference, Version 1.0, has been updated and
is available by anonymous FTP to networking.cary.ibm.com (also known as
ibmstandards.cary.ibm.com) under the name of
pub/standards/aiw/dlur/dlur6.psbin - the file is a PostScript file, but
treat it as binary when you get it and print it.  There are also
compressed versions of the file (pub/standards/aiw/dlur/dlur6.zipbin and
pub/standards/aiw/dlur/dlur6.exebin) as well as a BookManager version
(pub/standards/aiw/dlur/dlur6.bookbin).

The items added in DLUR-6 are:

** 1) added DLUS-served LU registration interaction with central
      resource registration

      When the DLUR sets the DLUS-Served LU Indicator on in CV X'80' of
      the Register Resource (X'12C3') GDS variable, it must also do
      something to prevent the DLUS-served LUs from being registered at
      the Central Directory Server.  The NNS can implement option set
      1116 to handle these resources, but the CDS doesn't have the
      ability to properly handle these resources once registered at the
      CDS.

      The document will be updated to include the following:

          When the DLUR sets the DLUS-Served LU Indicator on in CV X'80'
          of the Register Resource (X'12C3') GDS variable, it must also
          reset the Central Resource Registration Request Indicator.
          Both indicators reside in the same byte in CV X'80'.

** 2) editorial changes - not marked with change bars

      a) (appendix X) added index
      b) (3.1.1) added "Notations Used In Diagrams" section
      c) (figure 5-12, step 10) changed "DLUS" to "other DLUR"
      d) (figure 10-3, step 1) changed "UNBIND" to "BIND"
      e) (figure 10-11, step 1) changed "BIND" to "UNBIND"
      f) (13.1.3) changed "... send an ACTPU to the PU specified in
         the REQACTPU RU ..." to ... send an ACTPU to the PU specified
         in the REQACTPU's corresponding FID2 Encapsulation (X'1500')
         GDS variable
      g) (13.1.4) made same change as REQACTPU for REQDACTPU
      h) (too numerous to list) made terminology politically correct,
         e.g., "sense code" changed to "sense data"
               "intercluster link" to "intersubnetwork TG"
               "subvector" to "subfield"
               "GDS" to "GDS variable"
      i) (ditto) spelled out acronyms, added trademarks, corrected
         crooked quotation marks, apostrophes, hexadecimal numerical
         representations, ...
         (free advice: think more carefully than I did about giving
         a technical writer access to your source files while you're
         on a long vacation)
      j) (appendix D) formats polished up editorially
      k) shut off all change bars except those specifically for DLUR-6
