Hi Tyson,

Just change

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cdm="http://www.xyzcorp.com/ctypes"
xmlns="http://www.xyzcorp.com/Vessel"
targetNamespace="http://www.xyzcorp.com/Vessel"
elementFormDefault="unqualified" attributeFormDefault="unqualified">


to

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cdm="http://www.xyzcorp.com/ctypes"
xmlns="http://www.xyzcorp.com/Vessel"
targetNamespace="http://www.xyzcorp.com/Vessel"
elementFormDefault="qualified" attributeFormDefault="unqualified">

--------------------^^^^^^^^^

Your VesselBase element is declared locally and if you set the 
elementFormDefault to unqualified then all the local element 
declarations go to no namespace instead of target namespace and in your 
XML document the VesselBase element is in the 
http://www.xyzcorp.com/Vessel (target) namespace. To have the local 
elements in the target namespace you need to have the element form set 
to qualified.

Best Regards,
George
