It is not a big problem of course, I'm merely interrested in what is > the standard? This is unfortunately a subject with a lot of misnuderstandings. The "docyment type declaration" is "<!DOCTYPE xxx [ ...... ]>", which consists of the "document type definition", i.e. DTD. The dotted line correspond to the content of the DTD (more or less). So, an entity that claims to be a DTD does _not_ contain the DOCTYPE, the only place that a DOCTYPE can occur is at the beginning of a document instance (after the SGML declaration). Unfortunately the natural way to make an acronym of "docyment type declaration" is DTD, and this helps to foster the misunderstandings. SP and Jade are doing the right thing. There are some tool that either requier the DOCTYPE (wrong) or accept either format. In my view the accepting the DOCTYPE is a disservice in the long run since it hardly clears up the confusion. For a more complete and detailed description, consult the SGML Handbook.
