Customize object/element name with JAXB

I'm very new to JAXB, so I'm having trouble cracking this (I assume) very simple use case.

I have a set of schemas I got. I have no control over those, I cannot change them. In these schemas, I have declarations such as

<xs:complexType name="CustomerType">
    ...

I try to generate classes from these. So such a declaration becomes

@XmlType(name = "CustomerType", propOrder = {
    "field1",
    "field2"
})
public class CustomerType {
    ...

Then I need to use this class to create XML messages using a RestTemplate. The problem is, the object in the XML message is not supposed to be "CustomerType", it's supposed to be just "Customer". Like I said, I cannot edit the schemas. I also cannot directly edit the generated sources. I need some kind of external customization that tells either the source generating process, or the marshalling process, how to transform the names of the objects. Any advice will be greatly appreciated.

You can use bindings to customize class or property names. Typically you'll have a file like bindings.xjb like this:

<jaxb:bindings version="1.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    jaxb:extensionBindingPrefixes="xjc">

    <jaxb:bindings schemaLocation="schema.xsd" node="/xsd:schema">
        <jaxb:bindings node="xsd:customType[@name='CustomerType']">
            <jaxb:class name="Customer"/>
        </jaxb:bindings>
        <jaxb:bindings node="xsd:customType[@name='CustomerType']//xsd:element[@name='field1']">
            <jaxb:property name="f1"/>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

There are quite a few things you can customize with bindings (see this), but certainly not everything.

The way DTO objects are created is:

You define all the types at one place like: CustomerType, UserType, OrderType and so on.

You then create another schema and import appropriates XSD's within where you have defined multiple types. Then you actually use/aggregate these type definitions to create your XML Schema for objects . Something like below

<xs:complexType name="CustomerOrders">
<xs:element name="Customer" type="CustomerType">
<xs:attribute name="Orders" type="OrderType">
