An attribute model represents the model of a Ceylon attribute that you can read and inspect.

An attribute is a member value: it is declared on classes or interfaces.

This is both a ValueModel and a Member: you can invoke it with an instance value to bind it to that instance and obtain a Value:

class Outer(){
    shared String foo = "Hello";
}

void test(){
    Attribute<Outer,String> attribute = `Outer.foo`;
    Value<String> boundAttribute = attribute(Outer());
    // This will print: Hello
    print(boundAttribute.get());
}
