Predefined public render parameters

WebSphere Portal defines a set of portal-specific public render parameters to use with portal-specific state information within portlets. Public render parameters is a concept defined by the Java Portlet Specification 2.0. As opposed to private render parameters, public render parameters can be shared between portlets to implement coordination use cases. The main benefit of these predefined parameters is the portlet developer can rely on the Portlet API to work with portal_specific state information without using any portal-specific APIs or SPIs. For example, we can create a portlet render URI that addresses a portal page using the public render parameter that holds the portal page selection information.
