CAUTION:
Pages listed here can be the source of property values needed to compute an expression. However, properties on such named pages are not change-tracked.

This tab is wide. To display more of the content, click the collapse arrow in the portal to temporarily hide the navigation panel. When you finish working with this tab, click the expand arrow to display the navigation panel again.

Field Description
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.

Class Optional. Select the class of that page.
