/**
* Used by client and server side to create handler information
* from annotated class. The public methods all return a
* HandlerChainInfo that contains the handlers and role information
* needed at runtime.
*
*
All of the handler chain descriptors follow the same schema,
* whether they are wsdl customizations, handler files specified
* by an annotation, or are included in the sun-jaxws.xml file.
* So this class is used for all handler xml information. The
* two public entry points are
* {@link HandlerAnnotationProcessor#buildHandlerInfo}, called
* when you have an annotated class that points to a file.
*
*
The methods in the class are static so that it may called
* from the runtime statically.
