Ошибка при чтении XML

[Molecula]

Создал Аир приложение.
Пишу:

import flash.filesystem.*;
var file:File = File.userDirectory.resolvePath("AIR_Test/states.xml");
var fileStream:FileStream = new FileStream();
fileStream.open(file, FileMode.READ);
var prefsXML:XML = XML(fileStream.readUTFBytes(fileStream.bytesAvailable));
fileStream.close();

Выдаёт:

TypeError: Error #1088: The markup in the document following the root element must be well-formed.

Структура XML:

<?xml version="1.0" encoding="utf-8"?>
<root>
<xep>Hi!</xep>
</root>

Чт тут не так, не пойму.
