Problem conclusion

• IBM HTTP Server mod_include was updated to allow SSI
  documents
  to be migrated from DGW to IHS. mod_include was also updated
  to not duplicate characters after instances of '&'.
  
  The SSIOption option DollarSignExpansion was added to
  disable
  the expansion of $-prefixed variables.
  
  The SSIOption option DefaultEchoEncoding was added in 9.0 to
  allow users to configure a global default for the encoding
  of
  echo commands.
  
  The DGW-style variable expansion parser for SSI documents
  was
  updated on z/OS to only do variable expansions if they
  exactly
  match the syntax ´&var;´.
  
  This fix is targeted for IBM HTTP Server fix packs:
  - 9.0.5.0
  - 8.5.5.16
