As http://www.w3.org/TR/NOTE-sgml-xml says: # NET delimiters can be used only to close an empty element. In SGML # without the Web SGML Adaptations Annex, the NET delimiter # is declared as />. With this approach, XML is not allowing null # end-tags and is allowing net-enabling start-tags only for elements # with no end-tag. # # In SGML with the Web SGML Adaptations Annex, there # is a separate NESTC (net-enabling start tag close) delimiter. # This allows the XML <e/> syntax to be handled as a combination # of a net-enabling start-tag <e/ and a null end-tag >. # With this approach, XML is allowing a net-enabling start-tag only # when immediately followed by a null end-tag. In short, XML empty tags are proper SGML, including pre-1996 SGML, with some side constraints eliminating non-XML flexibilities like "<foo/bogus content>", which "nsgmls -xml" duly complains about. -- John Cowan http://www.ccil.org/~cowan cowan@c...
