   * The property is a simple value list. If property is a list property, the method will check to

   * a copy of the list value inherited from container or parent will be set locally on the element
   * itself.
   *
   * <p>This method is supposed to be used when we need to change the value of a composite property(
   * a simple list property ). These kind of property is inherited as a whole, so when the value
   * changed from a child element. This method will be called to ensure that a local copy will be
   * made, so change to the child won't affect the original value in the parent.
   *
   * @param ref a reference to a list property or member.
