Why is JAXB generating the wrong XML for my WCF service?

I have a WCF service that expects an object which I'll call StuffContainer. Our client is trying to generate an XML-serialized StuffContainer using JAXB, but it's coming out wrong. They're ending up with type names where they should have property names, so we're not able to deserialize it.

I know nothing about JAXB, but I gather it creates some auto-generated classes based on our XSD, which can be used to build the XML-serialized object.

Here's the relevant snippet of our auto-generated XSD:

<xs:complexType name="StuffContainer">
    <xs:sequence>
        <xs:element minOccurs="0" name="myStuff" nillable="true" type="tns:ArrayOfStuff"/>
    </xs:sequence>
</xs:complexType>
...
<xs:complexType name="ArrayOfStuff">
    <xs:sequence>
        <xs:element minOccurs="0" maxOccurs="unbounded" name="Stuff" nillable="true" type="tns:Stuff"/>
    </xs:sequence>
</xs:complexType>

Our client's code looks something like this:

ObjectFactory objectFactory = new ObjectFactory();

ArrayOfStuff arrayOfStuff = objectFactory.createArrayOfStuff();
JAXBElement<ArrayOfStuff> arrayOfStuffJAXBElement = objectFactory.createArrayOfStuff(arrayOfStuff);

StuffContainer stuffContainer = objectFactory.createStuffContainer();
stuffContainer.setStuff(arrayOfStuffJAXBElement);

Here's the XML they're getting:

<StuffContainer xmlns="..."><ArrayOfStuff>...</ArrayOfStuff></StuffContainer>

But I need it to be:

<StuffContainer xmlns="..."><myStuff>...</myStuff></StuffContainer>

I think this is because the JAXBElement<ArrayOfStuff> that they're getting from the objectFactory has its QName set to "ArrayOfStuff", and this ends up getting used instead of the property name myStuff. But like I said I know nothing about JAXB so I'm not sure what they should be doing differently.

Is there something either that I can change in the XSD, or that I can ask our client to change in their code, so that it generates the correct XML?

There may be multiple methods on the generated ObjectFactory class. The ones corresponding to nested elements have an entire path built into the method name.
