+                              Xhtml 1.0 strict standard and legacy rendering which reverts
+                              significant rendering changes made to conform to the Xhtml 1.1
+                              standards to their version 1.1 rendering. Default is "Transitional"
+                              to ensure conformance with the Xhtml 1.0 transitional standards
+                              while continue to render the name attribute on the form element.
+                              Note: Only rendering changes likely to break existing applications
+                              will be reverted to their old behavior. There is no mechanism to
+                              revert all changes made to conform to the Xhtml specification.
