  *                      adequately support CICS resources       *
  *                      encoded in Japanese EBCDIC codepages.   *

  ****************************************************************
  The CICS Atom feed support does not cope with EBCDIC codepages
  other than IBM1047. This is especially true of the Japanese
  EBCDIC codepages IBM930, IBM1390 and IBM5026, where the
  lowercase letters that commonly occur in XML documents are at
  different codepoints from those in other EBCDIC codepages.
  .
  Some of the problems are due to lack of support for Japanese
  EBCDIC in the ML and PI domains, and some of the problems are
  due to using EBCDIC with the XML System Service parser, which
  does not have extensive support for parsing in EBCDIC.
  
  Attempting to publish to CICS resources as feeds produces an
  AEXZ abend and attempting to POST data produces an HTTP 400
  response when trying to use Japanese EBCDIC codepages.
  

Problem conclusion

• XML services in the ML and PI domains have been modified to
  recognize and cope with the codepoint differences in the
  Japanese EBCDIC codepages.
  .
  Atomservice configuration file processing has been changed
  to convert the configuration data from EBCDIC to UTF-8 before
  parsing it. The codepage in which the configuration file is
  encoded is derived from the "encoding=" parameter in the XML
  signature, or is assumed to be IBM1047 if absent.
  .
  All parsing of the data received and generated by the CICS
  Atom support is now performed in UTF-8, although all the
  parameters and containers that are presented on the Atom
  service routine interface continue to be encoded in EBCDIC.
  
  
  
  The CMAC data set will also be updated to reinstate message
  DFHPI0914 and add message DFHML0510.
  
  The Version 4 Release 1 CICS Transaction Server for z/OS,
  CICS Messages and Codes manual (GC34-7035-00)
  will be updated as follows:
  
  Add the message DFHML0510 after message DFHML0509 in
  DFHMNnnnn messages section:
  
  DFHML0510 "DATE TIME APPLID USERID"
            "TRANID" XMLTRANSFORM "XMLTRANSFORM_NAME"
            FOR "{BUNDLE | ""ATOMSERVICE}"
            "OWNER_NAME" IS INCOMPATIBLE WITH THE
            LOCALCCSID.
  
  EXPLANATION:  XMLTRANSFORM "xmltransform_name" was not
  created as the associated XML binding is incompatible with the
  CCSID that is specified in the LOCALCCSID system initialization
  parameter.  The XML binding was generated without specifying a
  CCSID and therefore the binding is processed as compatible with
  US EBCDIC.  The LOCALCCSID value for this CICS region is not
  compatible with US EBCDIC.
  
  SYSTEM ACTION:  The XMLTRANSFORM is not created and the
  associated BUNDLE is placed in the DISABLED state.
  
  USER RESPONSE:  Regenerate the XSDBind file specifying the
  correct value for the CCSID parameter in the XML assistant.
  
  DESTINATION:  CMLO
  
  MODULE:  DFHMLXT
  
  XMEOUT PARAMETERS: date, time, applid,
  userid, tranid, xmltransform_name,
  {1=BUNDLE, 2=ATOMSERVICE}, owner_name

  The Version 4 Release 1 CICS Transaction Server for z/OS
  The Internet Guide (SC34-7021-00)
  'Atom feeds from CICS - start here' -
  'Setting up CICS definitions for an Atom feed' needs to be
  updated after the first paragraph under 'About this task' with
  the following:
      Ensure that the configuration file is in EBCDIC and it is
      assumed that it is provided in codepage 1047 unless
      'encoding=' has been specified.
