FieldDescription
Page Name Optional. Enter any page referenced by name on the Expressions tab.

Optionally, add a row with the keyword Top as the page name, to identify a top-level page. The Top keyword allows you to use the syntax Top.propertyref to identify properties, on other tabs of this rule form.

Declare Expression rules can apply to embedded pages that appear within top-level pages with various names. In such cases, you can use the keywords Top or Parent in the page name here. If the Page Context key part of this rule is not blank, this tab automatically includes a definition of the Top and Parent keywords.
