Are there available APIs that can be used to get the Embedded FWK content of a notification ?

I need to retrieve OAF Regions and show them (or at least get the information) in my external application.

Attribute HR_NTF_EMBEDDED_REGION refers to Framework Region JSP:/OA_HTML/OA.jsp?OAFunc=-HR_COMP_NTF_SS-&NtfId=-35815463-.

For example:

SELECT wf_notification.GetBody (35815463)

from dual;

gives:

Attribute HR_NTF_EMBEDDED_REGION refers to Framework Region JSP:/OA_HTML/OA.jsp?OAFunc=-HR_COMP_NTF_SS-&NtfId=-35815463-.

I need the actual body message not just the call to the region. I want somehow to at least retrieve or call somewhere OAFunc=-HR_COMP_NTF_SS-&NtfId=-35815463-. to be able to retrieve what I need.
