public class NamespaceTag
extends PortletTag

The namespace tag for the JSR 168 Portlet specification. This tag produces a unique value for the current portlet. This tag should be used for named elements in the portlet output (such as Javascript functions and variables). The namespacing ensures that the given name is uniquely associated with this portlet and avoids name conflicts with other elements on the portal page or with other portlets on the page.
