Description:
------------
I would like to see a content negotiation function in PEAR::HTTP that allows a program to list the acceptable mime types it can send and compare it to the user agent's preferences (ala language negotiation).

I've created a content negotiation function for HTTP v 1.4.0 that takes either a single content type or a list of types and compares them to the user agent's HTTP Accept header.  The best fit is then sent as the content-type header.

Test script:
---------------
<?php
require_once 'HTTP.php';
$mimeType = HTTP::negotiateContentType(
    array(
        'application/xhtml+xml',
        'application/xml'
    ),
    'UTF-8',
    'application/xml'
);
// add the xslt transformation if we're using application/xml
if ('application/xml' == $mimeType) {
    echo <<<_XML_
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="xhtml.xsl"?>
_XML_;
}
?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
...
</html>

Expected result:
----------------
the script is served via application/xhtml+xml if the user agent supports it, otherwise served as application/xml with a prolog and stylesheet at the top

Actual result:
--------------
n/a as this is a feature request

Thank you for taking the time to report a problem with the package.
Unfortunately you are not using a current version of the package -- 
the problem might already be fixed. Please download a new
version from http://pear.php.net/packages.php

If you are able to reproduce the bug with one of the latest
versions, please change the package version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PEAR.
