Description:
------------
After inserting a documentFragment into a document, the documentFragment becomes empty / loses its nodes.

I'm not sure if this is by design or not. I searched the W3C DOM spec for the specified behaviour. But it isn't clear to me if this is the way it should work or not. I also tested the same code with a normal element in stead of a documentFragment. Then it does works as I expect.

Also, I'm using PHP 5.0.4 and not PHP 5.0.5 Fedora hasn't released a PHP 5.0.5 package yet. I'm sorry!

Reproduce code:
---------------
<?php 

$xml = '<root><sometag>The quick brown fox jumps over the lazy dog</sometag></root>';

$doc = new DOMDocument();
$doc->loadXML($xml);

$sometags = $doc->getElementsByTagName('sometag');

while($sometag = $sometags->item(0)) {

	$docFrag = $doc->createDocumentFragment();

	while ($childNode = $sometag->firstChild) {
		$docFrag->appendChild($childNode);
	}

	echo 'Print documentFragment contents before replacing:<br />';
	foreach ($docFrag->childNodes as $childNode) {
		echo 'textContent:', $childNode->textContent, '<br />';
	}

	$sometag->parentNode->replaceChild($docFrag, $sometag);

	echo '<br />Print documentFragment contents after replacing:<br />';
	foreach ($docFrag->childNodes as $childNode) {
		echo 'textContent:', $childNode->textContent, '<br />';
	}
}

?>

Expected result:
----------------
Print documentFragment contents before replacing:
textContent:The quick brown fox jumps over the lazy dog

Print documentFragment contents after replacing:
textContent:The quick brown fox jumps over the lazy dog


Actual result:
--------------
Print documentFragment contents before replacing:
textContent:The quick brown fox jumps over the lazy dog

Print documentFragment contents after replacing:

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Read specs on DOMFragment carefully. Upon insertion to another node children of frag are moved.
