The <systemoutput> element represents computer output or responses to a command or situation. A generalized element, it represents any kind of output from the computer, so the author might want to choose more specific markup, such as <msgph> for messages from the application. The system output element is part of the DITA software domain, a special set of DITA elements designed to document software tasks, concepts and reference information.
See appendix for information about this element in OASIS document type shells.
