Description:
------------
In investigating a flaw in the CDATA change I notice that print_r isn;t working properly with open types

Reproduce code:
---------------
XSD 
===
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
        targetNamespace="http://www.example.org/test" 
        xmlns:tns="http://www.example.org/test">

    <complexType name="TestType" mixed="true">
        <sequence>
            <element name="jim" type="string"/>
            <any namespace="##any" processContents="lax"/>            
        </sequence>
    </complexType>
    
    <element name="test" type="tns:TestType"/>        
</schema>

XML
===
<?xml version="1.0" encoding="UTF-8"?>
<tns:test xmlns:tns="http://www.example.org/test" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
          xsi:schemaLocation="http://www.example.org/test cdata2.xsd ">
  <jim>xxx<![CDATA[some data and some <MoreXML></MoreXML>]]></jim>
  <entry>xxx<![CDATA[some data and some <MoreXML></MoreXML>]]></entry>
</tns:test>

PHP
===
$xmldas   = SDO_DAS_XML::create("cdata2.xsd");
$document = $xmldas->loadFile("cdata2.xml");
$root     = $document->getRootDataObject();
echo $xmldas->__toString() . "\n";
echo $xmldas->saveString($document);
print_r($root);

Expected result:
----------------
print_r($root) to provide similar information as is provided by saveString albeit in a different format.

Actual result:
--------------
object(SDO_DAS_XML)#1 {
