+ * 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

+ * For example if getBindingClass returns a class named "mypkg.FooBinding"

+ *
+ * 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
