JAXB External Custom Bindings Issue

Question

I have a very large schema that I am trying to bind using JAXB. The naming in the schema is very good, nor is the structure, so I was hoping to do some custom binding. When I went to start the custom binding in an external file XJC returns an error saying that the target node is empty. It works fine if I give it the schema location and point it at the root of the schema, but trying to access the first complex type doesn't work. My external custom bindings file is below, an excerpt from the XSD Follows it, as well as my error. Please keep in mind that I cannot modify the schema in anyway.
