    The docs don't mention it but this method performs escaping on the value. If you don't want that use createElement() instead.
    A quick note to anyone who is using character entities (e.g. ©) in this, and finding them automatically escaped. The correct thing to do here is to use the createEntityReference method (e.g. createEntityReference("copy");), and then appendChild this entity between text nodes.
    Example:
    <?php
    $copyright_text_1 = $this->document->createTextNode("Copyright ");
    $copyright_text_2 = $this->document->createTextNode(" Alex Kaye 2009");
    $copyright_symbol = $this->document->createEntityReference("copy");
    $copyright->appendChild($copyright_text_1);
    $copyright->appendChild($copyright_symbol);
    $copyright->appendChild($copyright_text_2);
    ?>
