Adobe version 7.0.0 and above have problem to Display the CDATA

I am getting some problem with the adobe reader 7.0 and above version.
Basically I have a XFDF file and there is a value tag where I have using CDATA for example
and another side I have pdf file where this data should show. But CDATA is working perfectly with the Adobe reader 6.0.2 and earlier versions also but it is not showing anything on Adobe version 7.0.0 and higher. Please let me know if this is an issue with adobe. If it is what is workaround of this problem. Thanks in advance
