Page names and reserved pages

A page is a data structure that holds name-value pairs. Most pages are named; the names of pages may arise from any of four sources:

Valid page names

A page name can contain only letters, digits, and the underscore character. Start the page name with a letter.

Several keywords identify elements in specific operations. Using keywords as a page name is not recommended: param, local, locate, primary, steppage, mysteppage, top, parent, or current.

Do not use any of the following names or patterns as a page name, where an asterisk indicates one or more characters: pxNode, pxRequestor, pxThread, LISTVIEW_*, locate* prompt*, $*, px*, pz*, or py*.

Special page name prefixes

You can't use certain prefixes and keywords as page names, as they have a special meaning:

The prefixes D_ and Declare_ in a page name indicates a data page, a page that is created and updated only by Data Page rules. The properties on this page are "read-only" to normal requestor processing. To avoid confusion with such pages , don't create pages named Declare_zzzzz or D_zzzzz in other processing.

Except as noted, case is not significant in keywords: Param.Country, PARAM.Country and param.Country all reference the same value.

Page names used by convention

Many standard activities and other standard rules use these page names by convention. To utilize these standard rules, follow these naming conventions in the rules you create.
