Description:
------------
It appears that cloning a SimpleXML object will not produce the same XML output on asXML() as the original object. The original will output the XML header and a line break after the XML while the cloned object is missing these.

Reproduce code:
---------------
<?php
$simplexml = new SimpleXMLElement("<root />");
$simplexml->path->to->node = "Zend";

$simplexml_2 = clone $simplexml;

echo "|{$simplexml->asXML()}|\n|{$simplexml_2->asXML()}|";

Expected result:
----------------
|<?xml version="1.0"?>
<root><path><to><node>Zend</node></to></path></root>
|
|<?xml version="1.0"?>
<root><path><to><node>Zend</node></to></path></root>
|

Actual result:
--------------
|<?xml version="1.0"?>
<root><path><to><node>Zend</node></to></path></root>
|
|<root><path><to><node>Zend</node></to></path></root>|

I got the same result when using the snapshot, as well as version 5.2.8.

The issue appears to be the cloned node doesn't have a document pointer as its ultimate parent. Attached patch should fix that.

Rob, could you have a look at this tiny patch?

The asXML() method is special in regards to the document element as it treats it 
as a document node for simple trees. A clone of a document element is a regular 
element (a document can only have 1) and does not get special treatment.

Patch breaks in memory tree. Either manually add the XML declaration to the clone 
or import to dom and clone the document and work off the new document.

Is there a reason this is marked as won't fix? I ran into this today, and it 
causes basic expected behavior such as:

$simplexml2 = clone $simplexml;
$simplexml->asXML() == $simplexml2->asXML();

to fail (returns false)
