Is libxml2 invoked whenever Kannel fetches a XML file

Greetings,
          I am posting this question here because it
          involves the architecture and the internal
          working of Kannel.

          In case this article looks long I have given a
          brief summary at the end. The lengthy paragraphs
          that are seen below could not be helped. I am
          trying to be as brief as possible without
          cutting the details.

          I downloaded the hello.wml file from the wapit.com
          site which is used as a test file for the fakewap
          application. I renamed hello.wml to hello.xml and
          invoked the same via a Ericsson R380 emulator (the
          IP address of the machine where Kannel is installed
          was set as the gateway address in the Ericsson emulator)

          I got Error message "Browser cant read text/html content"

          Next I copied a wap.xml file which was stored in the
          $LIBXML_HOME/test folder(I assume this XML file outputs
          WAP content) to the location where my Apache http
          server looks for requested files. I tried to invoke
          wap.xml in the Ericsson emulator, but again the same
          result- "Browser cant read text/html content"

          I checked the Kannel logs both times, after a
          series of Octet strings the ending line was:

          "Fetched URL/<xml-file-name> (text/html,charset="")

          Refusing to give up I was bent upon making Kannel
          extract the WAP content out of any well-formed XML
          file.

          So I configured the XML engine Cocoon to process
          all XML requests sent to Apache. In a sample XML
          file lying in the Cocoon folder I replaced all HTML
          tags to WML tags and placed it in the DocumentRoot
          of Apache. A third invocation of the XML file (.i.e
          the sample Cocoon XML file outputting WAP content)
          should have made Kannel recognize the output and
          succesfully pass it on to Ericsson R380 emulator.
          BUT again "Browser cant read text/html content"

          Thoroughly frustrated now I wrote a servlet program
          which outputs WAP content and invoked the servlet
          via Kannel, this time I hit the jackpot Ericsson
          R380 displayed the servlet's output. I called
          hello.wml (mentioned above) and again Ericsson
          is displaying the output.

          All these experiments lead me to believe that
          whenever Kannel sees a .xml extension in the URL
          it fetches the output of the XML file and(even if
          it is proper WAP content) passes this output to
          the GNOME XML library. This in turn fails the
          OUTPUT of the XML files I have been trying to invoke.

          Any diagnostic help- as to why Kannel fails to
          recognize the content-type of the XML files
          and labels the content-type as text/html even
          though these XML files output proper WAP
          content- would be appreciated.

          To help the people here I have drawn a small
          diagram which explains the short setup that I
          have on my system:

I am summarizing the actions once more here:

1) RENAMED hello.wml TO hello.xml FILE. BUT text/html

2) COPIED SAMPLE libxml2 (WAP-GENERATING) XML FILE
   TO APACHE DOCUMENTROOT STILL text/html

3) CONFIGURED XML ENGINE COCOON WITH APACHE. IN
   SAMPLE COCOON XML FILE REPLACED HTML TAGS
   WITH WML TAGS. BUT STILL text/html

4) WROTE A SERVLET PROGRAM, SET CONTENT-TYPE
   AS text/vnd.wap.wml AND HURRAH OUTPUT OF
   SERVLET SEEN IN ERICSSON R380

5) CONCLUSION: WHENEVER KANNEL SEES .xml
   EXTENSION, FETCHES OUTPUT AND PASSES
   IT ON TO libxml2. GNOME XML LIBRARY
   FAILS TO PROCESS OUTPUT AND LABELS
   IT AS text/html

 Thanks in advance.
