Description
A systemitem identifies any system-related item
      or term. The class attribute
      defines a number of common system-related terms.
Many inline elements in DocBook are, in fact, system related. Some
      of the objects identified by the class attribute on
      systemitem may eventually migrate out to become
      separate inline elements, and some inline elements may migrate into
      systemitem.
Processing expectations
Formatted inline.
