positive.code: In a managed domain, the XML files are found in the
  `domain/configuration` directory. There are two types of configuration
  files – one per host, and then a single domain-wide file managed by the

  processes in a managed domain, see <<Operating_modes,Operating

  bulk of the settings that should be applied to the servers in the domain
