CSS Validator Error

Dear Ladies and Gentlemen,

maybe I found an error while executing your CSS Validator.

Reference File 1: 

  
http://www.soziologie.uni-halle.de/unger/scripts/workshop_internet/main_first.shtml
   CSS validator works correct.

Reference File 2:

 
http://www.soziologie.uni-halle.de/unger/scripts/workshop_internet/main_plan.shtml
  CSS validator does not work correct.
  Validator Error: 
    Target:
http://www.soziologie.uni-halle.de/unger/scripts/workshop_internet/main_plan.shtml
    Please, validate your XML document first!
    Line 1
    Column 3
    The markup declarations contained or pointed to by the
    document type declaration must be well-formed.

Both files do not differ logically. The only difference is the document
type
definition:

Reference File 1:

<?xml version="1.0" encoding="iso-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="de" xml:lang="de">
<head>

Reference File 2:

<?xml version="1.0" encoding="iso-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
   "../../dtd/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="de" xml:lang="de">
<head>

Please not the different situation of the xhtml1-transitional.dtd file,
but I think that the way used by me is the specified one (the specified
file exists).

The W3 XHTML validator cannot find any error.

What is wrong?

I thank you for your endeavour in advance.
