+/**
+ * This annotation can be applied to the value() element of an annotation that
+ * is annotated as a TypeQualifier. This is only appropriate if the value field
+ * returns a value that is an Enumeration.
+ * 
+ * <p>
+ * Applications of the type qualifier with different values are exclusive, and
+ * the enumeration is an exhaustive list of the possible values.
+ * 
+ * <p>
+ * For example, the following defines a type qualifier such that if you know a
+ * value is neither {@literal @Foo(Color.Red)} or {@literal @Foo(Color.Blue)},
+ * then the value must be {@literal @Foo(Color.Green)}. And if you know it is
+ * {@literal @Foo(Color.Green)}, you know it cannot be
+ * {@literal @Foo(Color.Red)} or {@literal @Foo(Color.Blue)}
+ * 
+ * <pre>
+ * &#064;TypeQualifier
+ * &#064;interface Foo {
+ * 	enum Color {
+ * 		RED, BLUE, GREEN
+ * 	};
+ * 
+ * 	&#064;Exhaustive
+ * 	Color value();
+ * }
