Class declaration

[negerns]

I have been testing/configuring a UML tool to generate D classes/files 
when I came across D's class attributes scope and final. I wondered if D 
classes have other attributes like public, private, protected. So I 
tried it and tested some D source codes. Here is one that I tried:

private protected public class A {
     public this() { }
}

void main() {
     auto a = new A();
}

This code was successfully compiled using dmd 1.021 without errors or 
warnings, much to my surprise. Could anyone please tell me why is this so?
