Normally an XML document will have a distinct root element. Some vocabularies
have a set of possible root elements. I assume that your case is the latter:
you have an X3D document but its root element can be any element from a
set of predefined root elements. This is a fairly common scenario and the
way to handle this is described in the C++/Tree Mapping Wiki FAQ #2.2[1]
