Using JAXB binding extensions in wsimport

问题

I know how to enable extensions in a plain JAXB bindings file - list them in the root element's extensionBindingPrefixes:

<jaxb:bindings 
    version="1.0"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    jaxb:extensionBindingPrefixes="xjc"
    ...>

However, a JAX-WS bindings file doesn't have anywhere to put this attribute.

<jaxws:bindings
    version="2.0"
    xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    wsdlLocation="../wsdl/schema.wsdl"
    ...>

It cannot go in the root, nor in any of the nested jaxb:bindings elements.

How are you supposed to enable binding extensions?
