Stax2OutputFactoryProvider (Stax2 API 4.1 API)

```
public interface Stax2OutputFactoryProvider
```
Simple interface to be used for registering objects that can construct XMLOutputFactory2 instances with OSGi framework. The added indirection (provider constructing factory) is needed because of impedance between OSGi service objects (which are essentially singletons) and Stax/Stax2 factories which are not.
Note: implementations of provider should NOT use introspection via XMLOutputFactory.newInstance() as it will not work with OSGi. Instead, providers should directly construct instances of concrete factory they represent. That is, there will be one provider implementation per concrete Stax/Stax2 implementation
