What part of the C++ specification restricts argument dependent lookup from finding function templates in the set of associated namespaces? In other words, why won't the following compile?

namespace ns {
    struct foo {};
    template<int i> void frob(foo const&) {}
}

int main() {
    ns::foo f;
    frob<0>(f);
}
