Description

A Parameter identifies something passed from one part of a computer system to another. In this regard Parameter is fairly generic, but it may have a more constrained semantic in some contexts (for example in a ParamDef).

In an document that describes more than one kind of parameter, for example, parameters to functions and commands, the Class attribute can be used to distinguish between them, if necessary.

Processing expectations

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

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