It is the right DTD but it has probably been read using sgml-mode 
instead of xml-mode. I don't know how that could happen. In some 
earlier mail you used a precompiled dtd (.ced) file. If that is the 
case try removing that and PSGML should parse the DTD from source.

The problems are consistent with the DTD parsed in wrong mode. I tried 
going to the main file and executing sgml-mode and re-parsing the DTD 
and then load the chapter. I get the same behavior.

The code that interprets sgml-parent-document has lax error checking. I 
think that

     sgml-parent-document:("LEDATutorium.xml" "book" ("chapter") "book")

which is ill formed, is interpreted the same as

     sgml-parent-document:("LEDATutorium.xml" "book" ("chapter"))

Further if any element in the inner parentheses ("chapter") are 
undefined, this is not detected but later you can get an assertion 
failure.  If the DTD has been parsed as SGML, then "chapter" will be 
undefined as the element is named "CHAPTER".

That was just a side point as sgml-parent-document should be 
("LEDATutorium.xml" "book" "chapter")
in this case.
