    - #### isValueReference

          public static boolean isValueReference(String value)

      Return true if the specified string contains an EL expression.

      NOTICE This method is just a copy of `UIComponentTag#isValueReference(String)`, but it's required because the class UIComponentTag depends on a JSP 2.1 container (for example, it indirectly implements the interface JspIdConsumer) and therefore internal classes shouldn't access this class. That's also the reason why this method is inside the class ContainerUtils, because it allows MyFaces to be independent of a JSP 2.1 container.
