Description

CO is an empty element holding information describing a one-dimensional callout area specification embedded in a code example. It has Label and Linkends attributes, and common attributes with ID required.

Processing Expectations

CO appears in the code example, either in a ProgramListing or a Screen; at or pointing graphically to its position, the value of the Label attribute should be rendered. Its Linkends attribute holds pointers to related information; its ID attribute allows the construction of pointers to its location. Both methods may be used to link callouts with locations in code examples, but CO should not be used within ProgramListingCO or ScreenCO; if it is, the results are undefined.

Parents

These elements contain CO: ProgramListing, and Screen.

Attributes

Label

Label holds an identifying number or string to be output in some manner when the element it is applied to is rendered.

Linkends

IDs of targets pointed to by this element.
