/**
 * Creates {@link PipelineAssembler}.
 *
 * 
 * To create a pipeline,
 * the JAX-WS runtime locates {@link PipelineAssemblerFactory}s through
 * the {@code META-INF/services/com.sun.xml.ws.api.pipe.PipelineAssemblerFactory} files.
 * Factories found are checked to see if it supports the given binding ID one by one,
 * and the first valid {@link PipelineAssembler} returned will be used to create
 * a pipeline.
 *
 * 

 * TODO: is bindingId really extensible? for this to be extensible,
 * someone seems to need to hook into WSDL parsing.
 *
 * 
 * TODO: JAX-WSA might not define its own binding ID -- it may just go to an extension element
 * of WSDL. So this abstraction might need to be worked on.
 *
 * @author Kohsuke Kawaguchi
 * @deprecated
 *      Use {@link TubelineAssemblerFactory} instead.
