Represents an annotation.
An annotation associates a value with each element of an annotation type.
Sure it ought to be called "Annotation", but that clashes with
java.lang.annotation.Annotation.
This is NOT part of any supported API.
If you write code that depends on this, you do so at your own risk.
This code and its internal interfaces are subject to change or
deletion without notice.
