What is the need for specifying the document element in an XML document declaration? It is my understanding that in SGML elements may be omitted, so if the outermost element might be <BODY> but <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> tells the processor that HTML is the document element, and that <HTML>, <HEAD>, <TITLE>, etc. are implicitly present. In XML, elements cannot be omitted, so looking at the document element should be sufficient. So is the requirement for a document declaration name simply for compatibility with SGML, or is there another reason? Ari.
