Just wanted to point out that if you do the following code in php, you can generate a simple php page with a stylesheet.
<?php
    $res = xmlwriter_open_memory();
    xmlwriter_set_indent_string($res, "\t");
    xmlwriter_start_document($res);
    xmlwriter_write_pi($res, "xml-stylesheet", "type=\"text/xml\" href=\"yourstyle.xsl\"");
    xmlwriter_end_document($res);
    $string = xmlwriter_output_memory($res);
    echo $string;
?>
This results in the following:

Content-type: text/html
<?xml version="1.0"?>
<?xml-stylesheet type="text/xml" href="yourstyle.xsl"?>
