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 be inline elements of their own accord…and vice versa.

Processing expectations

Formatted inline. The MoreInfo attribute can help generate a link or query to retrieve additional information.

(4.0) Future Changes

In DocBook V4.0, the content model of SystemItem will be constrained to (#PCDATA | Replaceable | InlineGraphic).

Also, the EnvironVar and Prompt values of Class will be discarded (use EnVar and Prompt instead).
