+
+            This class is used to provide simple support for adding grouped
+            pdf writer structured element information like used in sd from
+            unomodel.cxx where a ViewObjectContactRedirector is used to add
+            such information for diverse objects.
+            This primitive encapsulates these and the VCLPdfRenderer uses it
+            to apply the needed infos directly to the pdf export in a compatible
+            way.
+            If a renderer ignores this, it just decomposes to its child
+            content.
