By my interpretation of the standard, this is not actually required, only recommended. SGMLS agrees: it issues a warning if it sees <!element foo - - EMPTY> in the DTD but it does flag the document as non-conforming. According to 7.3.1 and 11.2.2, the parser doesn't even examine the tag omission parameters for EMPTY elements or those with a non-#IMPLIED CONREF attribute. (It would be nice to be able to turn this warning off in SGMLS/SP though, especially for elements with CONREF attributes; I'd like to be able to specify that the end-tag is always required if no content reference attribute is supplied. But that has nothing to do with XML...) --Joe English jenglish@crl.com
