+ * A BindingActivator adds an SCA binding type to the Tuscany runtime.
+ *
+ * The SCDL XML used for the binding is derived from the name of the
+ * class returned from the getBindingClass method - the package name and
+ * any trailing "Binding" string is removed, leading upper case characters
+ * are converted to lowercase, and the suffix "binding." is added.
+ * For example if getBindingClass returns a class named "mypkg.FooBinding"
+ * then the SCDL for the binding will be <binding.foo>.
+ *
+ * Attributes of the <binding.foo> SCDL are based on the getters/setters of
+ * the binding class. So if FooBinding had getBar/setBar then there
+ * would be an attribute name 'bar', for example, <binding.foo bar="xxx">.
+ *
+ * BindingActivator implementations may use constructor arguments to have
+ * Tuscany ExtensionPointRegistry objects passed in on their constructor.
+ * For example:
+ *
+ * public class MyBindingActivator implements BindingActivator {
+ * ServletHost servletHost;
+ * public MyBindingActivator(ServletHost servletHost) {
+ * this.servletHost = servletHost;
+ * }
+ * ...
+ * }
+ *
+ * BindingActivator implementations are discovered by the Tuscany runtime
+ * using the J2SE jar file extensions for service provider discovery. All
+ * that means is packaging the new binding type in a jar which contains a
+ * file META-INF/services/org.apache.tuscany.sca.extension.helper.BindingActivator and
