12.6.9. Sideline Flow Object Class

Use of this flow object requires the sideline feature.

A sideline flow object is used to contain flow objects that have an attachment area (see “Attachment Areas”) consisting of a line parallel to the placement direction. A sideline flow object has a single principal port which can contain both inlined and displayed flow objects. For each display area produced by its content, the sideline flow object adds an attachment. For each inline area produced by its content, the sideline flow object annotates that area so as to cause the paragraph in which the flow object occurs to add an attachment area to the line in which that inline area occurs.

NOTE 78: Sidelines are often used to mark changes.

This is illustrated in Figure 14.

A sideline flow object has the following characteristics:

Sidelines on consecutive areas in a single area container which have no space between them should be drawn as a single line.
