/**
* Factory to create {@link JAXBContext}.
*
*
* JAX-WS uses JAXB to perform databinding when you use the service endpoint interface, and normally
* the JAX-WS RI drives JAXB and creates a necessary {@link JAXBContext} automatically.
*
*
* This annotation is a JAX-WS RI vendor-specific feature, which lets applications create {@link JAXBRIContext}
* (which is the JAXB RI's {@link JAXBContext} implementation.)
* Combined with the JAXB RI vendor extensions defined in {@link JAXBRIContext}, appliation can use this to
* fine-tune how the databinding happens, such as by adding more classes to the binding context,
* by controlling the namespace mappings, and so on.
*
*
* Applications should either use {@link UsesJAXBContextFeature} or {@link UsesJAXBContext} to instruct
* the JAX-WS runtime to use a custom factory.

/**
* Called by the JAX-WS runtime to create a {@link JAXBRIContext} for the given SEI.
*
* @param sei
* The {@link SEIModel} object being constructed. This object provides you access to
* what SEI is being processed, and therefore useful if you are writing a generic
* {@link JAXBContextFactory} that can work with arbitrary SEI classes.
*
* @param classesToBind
* List of classes that needs to be bound by JAXB. This value is computed according to
* the JAX-WS spec and given to you.
*
* The calling JAX-WS runtime expects the returned {@link JAXBRIContext} to be capable of
* handling all these classes, but you can add more (which is more common), or remove some
* (if you know what you are doing.)
*
* The callee is free to mutate this list.
*
* @param typeReferences
* List of {@link TypeReference}s, which is also a part of the input to the JAXB RI to control
* how the databinding happens. Most likely this will be just a pass-through to the
* {@link JAXBRIContext#newInstance} method.
*
* @return
* A non-null valid {@link JAXBRIContext} object.
*
* @throws JAXBException
* If the callee encounters a fatal problem and wants to abort the JAX-WS runtime processing
* of the given SEI, throw a {@link JAXBException}. This will cause the port instantiation
* to fail (if on client), or the application deployment to fail (if on server.)
