Problem with dom_import_simplexml on newly created SimpleXML nodes
I'm working on a class extending `SimpleXMLElement`:

    class MyXML extends SimpleXMLElement {
        public function cdata($text) {
            $node = dom_import_simplexml($this);
            $owner = $node->ownerDocument;
            $node->appendChild($owner->createCDATASection($text));
            return $this;
        }
    }

Since it's an `SimpleXMLElement`, I can dynamically create XML nodes inside it:

    $xml = new MyXML('<foo/>');
    $xml->bar = 'Test';
    print $xml->asXML(); // <foo><bar>Test</bar></foo>

But when I try to run this:

    $xml = new MyXML('<foo/>');
    $xml->bar->cdata('Test');

I get:

    Warning: dom_import_simplexml(): Invalid Nodetype to import in [..]

However, if I force the `SimpleXMLElement` node to be created before running `cdata()`, it works again:

    $xml = new MyXML('<foo/>');
    $xml->bar = '';
    $xml->bar->cdata('Test');
    print $xml->asXML(); // <foo><bar><![CDATA[Test]]></bar></foo>

I'm curious if what I found is a bug, and if there is any way to work around it without "priming" the node first.
