Description:
------------
I produced a new mozsearch.inc of php.net website. It's based on Opensearch (A9) and works in Mozilla and IE7.

Current: http://darkstar.ist.utl.pt/php/include/mozsearch.inc

Reproduce code:
---------------
<SearchPlugin xmlns="http://www.mozilla.org/2006/browser/search/">
<ShortName>PHP.net</ShortName>
<Description>PHP.net - Search</Description>
<InputEncoding>UTF-8</InputEncoding>
<Contact>gothicx@gmail.com</Contact>
<Image width="16" height="16"><?php echo $MYSITE; ?>images/phpnetsearch.png</Image>
<Developer>Marco Rodrigues</Developer>
<Url type="text/html" method="GET" template="<?php echo $MYSITE; ?>manual-lookup.php">
  <Param name="pattern" value="{searchTerms}"/>
  <Param name="opensearch" value="yes"/>
</Url>
<SearchForm><?php echo $MYSITE; ?></SearchForm>
</SearchPlugin>

Expected result:
----------------
Use search plugin to find functions information more easily. At Mozilla Firefox and IE7 also.

Actual result:
--------------
Only works for Mozilla and it's Sherlock, not Opensearch.
