Margin rules

Margin rules, or change bars, are annotations drawn alongside content, often to indicate where material has been added or changed.

To use margin rules the layout must define where they will be positioned.

A margin rule is created by either:

There is a special type of marker intended to indicate that content has been deleted. This type of marker does not have a start and end because it is used to mark a single point. Deletion markers can only be created by using the <marginrule/> command.

The appearance of margin rules and deletion markers can be controlled by using the <marginrule-properties/> command.
