When having data in the header of a html-file, witch is not enclosed as
property, but as content firefox works in quirks mode and moves that data into
the body.
This is not a good thing if you want to extend some xhtml-file with some metadata.

Its possible to hide the information using a special ccs instruction per case,
but this is not the sence behind.

Reproducible: Always

Steps to Reproduce:
<html xmlns="..." xmlns:ns="...">
 <header>
  <title>Title</title>
  <ns:foo>Data</ns:foo>
 </header>
 <body>
  &nbsp;
 </body>
</html>
Actual Results:  
<html xmlns="..." xmlns:ns="...">
 <header>
  <title>Title</title>
 </header>
 <body>
  <ns:foo>Data</ns:foo>
  &nbsp;
 </body>
</html>

Expected Results:  
<html xmlns="..." xmlns:ns="...">
 <header>
  <title>Title</title>
  <ns:foo>Data</ns:foo>
 </header>
 <body>
  &nbsp;
 </body>
</html>

This is needed ie. when trying to include Geoinformation into an xhtml-file. The
syntax is:

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:geo="http://www.w3.org/2003/01/geo/wgs84_pos#">
 <header>
  <title>Title</title>
  <geo:Point>
   <geo:lat>45</geo:lat>
   <geo:long>30</geo:long>
  </geo:Point>
 </header>
 <body>
  Content of body.
 </body>
</html>

This is ie. a need for geoinformational searchengines witch can be used in cases
like finding a hotel/restaurant next to you're current location. It coul'd also
be viewed by an (firefox-)plugin to be able to see the location on a worldmap.
I suspect the answer is: "don't serve such documents as text/html". 

From http://www.w3.org/TR/xhtml-media-types/#text-html 

"In particular, 'text/html' is NOT suitable for XHTML Family document types that
adds elements and attributes from foreign namespace..."

I know that, so I've included the following line into the Header:
   <meta http-equiv="Content-Type" content="application/xhtml+xml" />

I've no possibility to change the behavior from the (Apache-)Server of my
Webhoster witch would be the best solution at all. Also changing the
Fileextension to .xhtml will help, but then I have the Problems that (1) the
Tools I've in use (specially blogger.com) won't support that and (2)
Internet-Explorer can't show them without a registry-hack. So I would need to
have a copy of each and every .xhtml file with an .html Extension.

Considering such practical Problems, I would recommend to let the Meta-Element
overwrite the RFC2616 (HTTP) Response Header, whitch is afaik the original
purpose of http-equiv="Content-Type".

That would violate the HTTP and XHTML specifications.

Marking invalid; the behavior here is exactly what XHTML requires.
