Ah. Pardon me my ignorance. Different syntax for empty elements
in XML or SGML was a nuisance anyway, so this seems to be a one more thing

If i understood this correctly, SAX is also not designed for
interoperatibility. If you want to generate pre-WebSGML from
XML using SAX (and accept that lexical information is not preserved), you
still would need the ability to detect empty declared elements.
