RQM 5.0 and a customer adapter cannot register with a 415

We have a customer adapter that we are trying to register with RQM.  We can connect ot the server and verify that the adapter does not yet exist.  When we try to register the adapter attempting to PUT the following data

<?xml version="1.0" encoding="utf-8"?>
