Description:
------------
Using apache 2.0, I added a content handler for XML files so they get processed by a PHP script.  I want to include XML files into an output buffer but I get an "Unexpected T_STRING" parse error from the "<?xml version="1.0"?> processing instruction.  This is because PHP is, incorrectly, parsing all processing instructions as PHP code.

httpd.conf: 
...
AcceptPathInfo On
...

.htaccess:
...
Action process ./process.php
AddHandler process .xml
...

Reproduce code:
---------------
process.php:
<?php
ob_start();
include($_SERVER("PATH_TRANSLATED"));
ob_end_flush();
?>

content.xml:
<?xml version="1.0"?>
<tag>some data</tag>



Expected result:
----------------
I expect to see the following in "view source" in my browser:

<?xml version="1.0"?>
<tag>some data</tag>


Actual result:
--------------
PHP incorrectly attempts to parse the XML declaration at the beginning of content.xml giving an "Unexpected T_STRING, line 1, content.xml" error.
