Are you talking about the id="..." attribute on MXML tags? All it does it autogenerate a public var in the class. For example, if you write <mx:Button id="b"/> in an MXML component then the autogenerated AS class has the instance var public var b:Button; So if you plan on dynamically instantiating components instead of statically declaring them with tags, you simply declare your own var as above and then do b = new Button(); The difference between this approach and AJAX is that AS3 gets its performance gain over Javascript by having non-dynamic classes (where all properties and methods are declared at compilation time) in addition to to dynamic ones. Flex components are mostly non-dynamic for speed. So you simply declare variables to be the "id's" of the components you're going to create later. - Gordon

The ability to create IDs on-the-fly is very helpful in other technologies, such as AJAX.
