Creating properties to use as the source for data binding

When you create a property that you want to use as the source of a data binding expression, Flex can automatically copy the value of the source property to any destination property when the source property changes. To signal to Flex to perform the copy, you must use the [Bindable] data tag to register the property with Flex.
