Nothing in the XHTML DTD demands that <html> be > the root element; that knowledge comes from outside the DTD itself. It depends on what you mean. If you are validating, the root element must match the name declared in the DTD. From the XML Rec, section 2.8: "Validity Constraint: Root Element Type The Name in the document type declaration must match the element type of the root element." So a document type declaration **does** in fact require a specific named root element. But if you are including an external subset (say, the xhtml declarations), it's true that the external subset doesn't have to declare a root. If that's what you meant, your point is well taken.
