Then, we mention that some elements cannot contain objects > in the description of those elements. But then, you do not remove the ambiguity that is condemned in this thread. The greater element/element and greater element/lesser element distinctions are equivalent, albeit not identical. IIUC, you want three terms for elements (I am not even talking about secondary strings, which can hold objects that are not part of contents), and probably two for objects: terminal and non-terminal.
