The base page in HTML or XML text is the page that contains a property identified only by a period followed by a property name.
The base page generally the same as the primary page, unless the base page was reassigned through the withPage JSP tag or the With directive.
During stream processing, the system assembles output HTML (for display or correspondence) or output XML (for SOAP or other processing) from rule types such as Rule-Obj-HTML, Rule-HTML-Fragment, Rule-Obj-Corr, and others.
Late in this multistep process, the system interprets JSP tags directives and property references in the assembled stream in the context of the current clipboard.
If no page name is mentioned in the property reference or a keyword symbol for a property such as $THIS
is used, the system uses the current base page as the source of the property.
Do not confuse base page, used in stream processing, with base classes or the ultimate base class.
