HR Contact SOAP Response Normalization

In this challenge you will transform the output of a Web Service Consumer into a clean JSON contact object for a downstream REST consumer. You will practice navigating the structure that the Web Service Consumer exposes, XML namespace handling in DataWeave, basic string transformations, and reading a Mule application property.
