      The Binding ruleset contains a collection of good practices around usage of binding.

	<rule class="org.apache.flex.pmd.rules.binding.BindingUtilsRule"

		<example>
public class Controller extends FrontController
{
   public function Controller()
   {
   	 BindingUtils.bindSetter(setContent, value, "content"); // VIOLATION

	<rule class="org.apache.flex.pmd.rules.binding.ChangeWatcherRule"
		message="ChangeWatcher class uses hard coded strings to specify the attribute name, to listen to. Prefer listening to events or setters">

		<example>
public final class Title 
{
	private var watcher : ChangeWatcher; // VIOLATION
}		
		</example>

	<rule class="org.apache.flex.pmd.rules.binding.TooLongBindingExpressionRule"
		message="This binding expression is too long ({0} dots maximum, but {1} actually)">
