Removing CDATA around XML Adds Unwanted Escaping

I've tried to follow examples in other posts but they have issues. This seems like something that should have a straight forward solution. I use a web service that returns a <DATA> node that contains CDATA that interns contains the XML payload I need. I've managed to write the java mapping to strip out the <DATA> and the CDATA and it looks fine when I test it in the OM test tab. But when I run this through PI the XML inside the CDATA is all escaped and everything I do to use it throws errors. I seriously need to get this working and could use any help. Here is a sample of the XML...

<?xml version="1.0" encoding="UTF-8"?>

<ns0:MT_ExportPayload xmlns:ns0="http://isbdcapp86/Enablon7.8Train/rpc_literal.wsdl">

<Data><![CDATA[<?xml version="1.0" encoding="UTF-16" standalone="yes" ?>

<Document>

  <Record>

    <EmployeeID>ID000006150265</EmployeeID>

    <ApplicationUser>&lt;None&gt;</ApplicationUser>

    <LastName>Shi</LastName>

    <FirstName>Nansun</FirstName>

  </Record>

</Document>]]>

</Data>

</ns0:MT_ExportPayload>

OM Test Tab using my java map (code below) gives me this...

<Data>

<Document>

  <Record>

    <EmployeeID>ID000006150265</EmployeeID>

    <ApplicationUser>&lt;None&gt;</ApplicationUser>

    <LastName>Shi</LastName>

    <FirstName>Nansun</FirstName>

  </Record>

</Document>

</Data>

But when I look at logs (soap message logs), I see this note the XML preamble in the <DATA> and even my needed xml is escaped...

<enab:ExportDataResponse xmlns:enab="enablon"> <Data>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-16&quot; standalone=&quot;yes&quot; ?&gt;

&lt;Document&gt;

  &lt;Record&gt;

    &lt;EmployeeID&gt;ID000006150265&lt;/EmployeeID&gt;

    &lt;ApplicationUser&gt;&amp;lt;None&amp;gt;&lt;/ApplicationUser&gt;

    &lt;LastName&gt;Shi&lt;/LastName&gt;

    &lt;FirstName&gt;Nansun&lt;/FirstName&gt;

&lt;/Record&gt;

&lt;/Document&gt;</Data>

</enab:ExportDataResponse>

The Java map based on what I have found in other, somewhat old posts...
