OnMethodBoundaryAspect on Base class should be applied on all derived classes

[nine-2-five]

I have this:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, AllowMultiple = true)]
public class TracingAspect : OnMethodBoundaryAspect

But it is only applied when it's attributed to a derived class or method. I'd like to have it on a base class, and inherited by all derived classes.
Base class in my case serves only as a shared code "distributor", it doesn't have any inherited/overridden methods.
