        /** StructureTagPrimitive2D class

            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.
