Okay, what may be confusing me is that the SOAP message trace still shows the escaped characters. And, fails on the mapping that should execute next. I find it very difficult to see exactly what is happening with only the SOAP message trace and the log file so if anyone knows of other tools please share. So the SOAP message trace shows the escaped characters for the CDATA, but the CDATA is gone, and the log shows a fail (copy below) on the mapping (also below) that should be next which is a simple copy of the user's last name to a single string inside a very simple XML structure.
