Map Value rules - Completing the New or Save As form

A map value rule has two key parts.

Field	Description
Type	Select `Map Value` from the `Decision` category.
Applies To	Identify a class that is to contain this map value. The classes you can enter here may depend on the RuleSet you select. On the Restrictions tab of the Class form, a class rule may limit rules applying to that class to belong to one of an explicit list of RuleSets. Map value rules can apply to an embedded page. On the Map Value rule form, you can use the keywords `Top` and `Parent` in property references to navigate to pages above and outside the embedded page. If you use these keywords, include the class and absolute name — or a symbolic name using `Top` or `Parent` — on the Pages & Classes tab. See Property References in Expressions.
Map Name	Enter a name that's a valid identifier. Begin the name with a letter and use only letters, digits, and a dash character. See Entering identifiers.

For general information about the New form, see Completing the new rule dialog box. For general information on the Save As form, see How to enter rule keys using Save As.
