Yep, that looks like a bug...  Can you please file a bug at bugs.php.net?

The workaround is the write the following:

$node = $dom->createElement("foo");
$text = $dom->createTextNode( "which entities <i>does</i> it
escape & which doesn't it?");
$node->appendChild($text);
$root->appendChild($node);


While a little more to type, it's at least the official W3C way ;)
