HTML, XML, and XHTML are all descendants of SGML. They are what SGML has become today. SGML had a hierarchy of tags -- which ones would automatically close off others, so that it wasn't necessary to slavishly balance all the tag-bracketting. But the exact hierarchy would depend on the publisher's style definition for the document type. HTML still has such conventions, but now they seem to be considered error corrections instead of an intended feature. -- hendrik -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
