+/**
+ * Indicates whether or not a JDK specific type or package is an
+ * exported part of the JDK suitable for use outside of the JDK
+ * implementation itself.
+ *
+ * This annotation should only be applied to types and packages
+ * <em>outside</em> of the Java SE namespaces of {@code java.*} and
+ * {@code javax.*} packages. For example, certain portions of {@code
+ * com.sun.*} are official parts of the JDK meant to be generally
+ * usable while other portions of {@code com.sun.*} are not. This
+ * annotation type allows those portions to be easily and
+ * programmatically distinguished.
+ *
+ * <p>If in one release a type or package is
+ * <code>@Exported(true)</code>, in a subsequent major release such a
+ * type or package can transition to <code>@Exported(false)</code>.
+ *
+ * <p>If a type or package is <code>@Exported(false)</code> in a
+ * release, it may be removed in a subsequent major release.
+ *
+ * <p>If a top-level type has an <code>@Exported</code> annotation,
+ * any nested member types with the top-level type should have an
+ * <code>@Exported</code> annotation with the same value.
+ *
+ * (In exceptional cases, if a nested type is going to be removed
+ * before its enclosing type, the nested type's could be
+ * <code>@Exported(false)</code> while its enclosing type was
+ * <code>@Exported(true)</code>.)
+ *
+ * Likewise, if a package has an <code>@Exported</code> annotation,
+ * top-level types within that package should also have an
+ * <code>@Exported</code> annotation.
+ *
+ * Sometimes a top-level type may have a different
+ * <code>@Exported</code> value than its package.
