Selected DOCTYPE disregarded

I have three test pages:

<http://www.unics.uni-hannover.de/nhtcapri/temp/doctype1.html>
   without DOCTYPE

<http://www.unics.uni-hannover.de/nhtcapri/temp/doctype2.html>
   with DOCTYPE incorrectly after <html>

<http://www.unics.uni-hannover.de/nhtcapri/temp/doctype3.html>
   with DOCTYPE incorrectly after <head>

  [ Of course, this isn't for fun but I actually found such pages
    on the web. ]

What bothers me is that the validator disregards the manually selected
DOCTYPE for doctype2.html and doctype3.html:

<http://validator.w3.org/check?uri=www.unics.uni-hannover.de/nhtcapri/temp/doctype1.html&doctype=HTML+4.01+Strict>

<http://validator.w3.org/check?uri=www.unics.uni-hannover.de/nhtcapri/temp/doctype2.html&doctype=HTML+4.01+Strict>

<http://validator.w3.org/check?uri=www.unics.uni-hannover.de/nhtcapri/temp/doctype3.html&doctype=HTML+4.01+Strict>
