The Sibling rules window shows all the rules that share the same second key part as the current rule. Not all of these are true siblings. This display is most useful for rule types with two key parts that have an Applies To class as the first key part.

The window might include rules in rulesets you cannot access, rules that are unavailable, and circumstanced.

Rows in the display correspond to Applies To values. Numbers in brackets show how many distinct rules (counting siblings, versions, circumstances, and so on) are in each class.

Columns identify rulesets and versions. Each cell that contains an icon indicates that a rule of that name and Applies To class exists, with an icon describing the rule availability.

You can do any of the following actions:

• Click the Circumstanced link, which appears for a rule with circumstance verions, to display the circumstance property and value.
• Select a value in the Applies To field to change its value and click Get Related Rules to view rules with the same second key part in other classes.
• Click Legend to view a legend for this window.
• Click Details to display information about the sibling rules.
