Where's the error? I don't think > it's with PSGML because with good DTD written by professionals it > works just fine. I haven't used PSGML/Emacs, but I can see that your DTD is invalid. The Mixed Content model is defined as:- [51] Mixed ::= '(' S? '#PCDATA' (S? '|' S? Name)* S? ')*' | '(' S? '#PCDATA' S ')' In particular, the mixed content model does not allow bracketed sub-sequences. When your DTD is expanded, your "ainhalt" content model would look like this: <!ELEMENT ainhalt ((#PCDATA | (tabelle | liste | bild | nsi | link | publikation)))* > This is not a legal, what you need is it to be resolved to this:- <!ELEMENT ainhalt (#PCDATA | tabelle | liste | bild | nsi | link | publikation)* > So you need to adjust your parameter entities accordingly.
