I can't seem to get instanceof or isAnnotationPresent to detect a
class annotation even though I've seen isAnnotationPresent documented
for this purpose. I'm using JRE1.6.0_05 on Vista.
So I'll leave as a simple marker interface for now, I'd be curious if
anyone else has any success with annotations.
I'll move the interface to kernel.
