## Description

`ComputerOutput` identifies lines of text generated by a computer program (messages, results, or other output).

Note that `ComputerOutput` is not a verbatim environment, but an inline.

### Processing expectations

Formatted inline. The `MoreInfo` attribute can help generate a link or query to retrieve additional information. It’s often presented in a fixed width font.

### Future Changes

The `InterfaceDefinition` element will be discarded in DocBook V4.0. It will no longer be available in the content model of this element.
