It seems that xmllint can't handle that extension:

/opt/gnu/bin/xmllint -valid --noout LEDATutorium.xml
LEDATutorium.xml:44: validity error: NOTATION attribute application 
reference an unknown notation "PDF"
<book lang="de">
                ^
chapter1.xml:6: validity error: NOTATION attribute application reference 
an unknown notation "PDF"
<chapter>
         ^
(using libxml version 20412)



This is a different error message from what I get without the above 
extension:

/opt/gnu/bin/xmllint -valid --noout LEDATutorium.xml
LEDATutorium.xml:752: validity error: Value "PDF" for attribute format 
of imagedata is not among the enumerated set
      <imagedata  align="center" format="PDF" 
fileref="Pictures/ArrayOfChar.pdf 
                                                     ^


nsgmls reports the file as valid now.
