If you are defining your component in MXML, then no, id cannot be private. When you define a component in MXML, the component class will inherit from whatever the main container class is, which in this case is Canvas. Canvas extends UIComponent, which defines the id attribute as being public. The only way to create a component with a private id attribute is to create the component in ActionScript, extend a subclass of UIcomponent, then override the id getter setter. And this goes for 'redefining' any built-in property of a UIComponent class.
