OSB 10gr3 XQuery with CDATA - how to best do this?

Question

Hi There,
I am writing an XQuery function to transform from one schema to another. My target schema has an attribute that is a string (xs:string), but the related protocol uses is for embedding another XML schema. Therefore I would like to treat the embedded value as an XML document using the CDATA command. I have tried using fn:concat and fn-bea:serialize but they do not work. There was an older thread :
Returning CDATA using XQuery in ALSB
in which the fn:inline is suggested, but this is not a valid function in the OSB10gR3 version.
Can somebody provide me with an idea about how to use CDATA in an xquery ? Here is an example of the non-working fn:concat implementation:
<ns0:abcRequest>
<ns0:abcRequest>
{fn:concat("<![CDATA[") }
{ $abcMessage/@* , $abcMessage/node() }
{fn:concat("]]>") }
</ns0:abcRequest>
<ns0:abcEgmId>{ xs:string( $abcEgmId ) }</ns0:abcEgmId>
<ns0:abcHostId>{ xs:int( $abcHostId ) }</ns0:abcHostId>
</ns0:abcRequest>
Any ideas for OSB 10g R3 would be much appreciated.
Thanks,
David.

Hi Anuj,
The serialize function does not escape the contents properly. It converts ">" to "Ambersand-G-T-Semicolon" (I had to spell them out since this forum had converted the characters back to the greater than symbol). I need to have the embedded CDATA and XML document untouched for subsequent processing on the side of the SOAP Provider (which I have no control over).
So I want to achieve:
<xmlElement>
<innerElement><![CDATA[<myEmbeddedXML><nextedElement>....</myEmbeddedXML></nextedElement>]]>
</xmlElement>
Does this make sense ?
Thanks,
David.
