Template specialization based on inherit class

Question

I want to make this specialized w/o changing main. Is it possible to specialize something based on its base class? I hope so.

-edit-

I\'ll have several class

Answer 1

And the short version now, 2014, using C++-11:

#include 

struct SomeTag { };
struct InheritSomeTag : SomeTag { };

template::value>
struct MyClass { };

template
struct MyClass {
    typedef int isSpecialized;
};

int main() {
    MyClass::isSpecialized test1;        /* ok */
    MyClass::isSpecialized test2; /* ok */
}
