XMLWriter::startDocument() writes the XML declaration.

Without XMLWriter::startDocument() :

<?php

$xml
= new XMLWriter();
$xml->openUri('php://stdout');
$xml->writeElement('message', 'Hello World!');
exit;

/*
Outputs :
<message>Hello World!</message>
*/
?>

With XMLWriter::startDocument() :

<?php

$xml
= new XMLWriter();
$xml->openUri('php://stdout');
$xml->startDocument();
$xml->writeElement('message', 'Hello World!');
exit;

/*
Outputs :
<?xml version="1.0"?>
<message>Hello World!</message>
*/
?>
