+/**
+ * Indicates that an annotated field or method is part of the {@linkplain
+ * Serializable serialization mechanism} defined by the
+ * <a href="{@docRoot}/../specs/serialization/output.html">
+ * <cite>Java Object Serialization Specification</cite></a>. This
+ * annotation type is intended to allow compile-time checking of
+ * serialization-related declarations, analogous to the checking
+ * enabled by the {@link java.lang.Override} annotation type to
+ * validate method overriding. {@code Serializable} classes are encouraged to
+ * use {@code @Serial} annotations to help a compiler catch
+ * mis-declared serialization-related fields and methods,
+ * mis-declarations that may otherwise be difficult to detect.
+ *
+ * <p>Specifically, annotations of this type should be
+ * applied to serialization-related methods and fields in classes
+ * declared to be {@code Serializable}. The five serialization-related
+ * methods are:
+ *
+ * <ul>
+ * <li>{@code private void writeObject(java.io.ObjectOutputStream stream) throws IOException}
+ * <li>{@code private void readObject(java.io.ObjectInputStream stream) throws IOException, ClassNotFoundException}
+ * <li>{@code private void readObjectNoData() throws ObjectStreamException}
+ * <li><i>ANY-ACCESS-MODIFIER</i> {@code Object writeReplace() throws ObjectStreamException}
+ * <li><i>ANY-ACCESS-MODIFIER</i> {@code Object readResolve() throws ObjectStreamException}
+ * </ul>
+ *
+ * The two serialization-related fields are:
+ *
+ * <ul>
+ * <li>{@code private static final ObjectStreamField[] serialPersistentFields}
+ * <li>{@code private static final long serialVersionUID}
+ * </ul>
+ *
+ * Compilers are encouraged to validate that a method or field marked with a
+ * {@code @Serial} annotation is one of the defined serialization-related
+ * methods or fields declared in a meaningful context and issue a warning
+ * if that is not the case.
+ *
+ * <p>It is a semantic error to apply this annotation to other fields or methods, including:
+ * <ul>
+ * <li>fields or methods in a class that is not {@code Serializable}
+ *
+ * <li>fields or methods of the proper structural declaration, but in
+ * a type where they are ineffectual. For example, {@code enum} types
+ * are defined to have a {@code serialVersionUID} of {@code 0L} so a
+ * {@code serialVersionUID} field declared in an {@code enum} type is
+ * ignored. The five serialization-related methods identified above
+ * are likewise ignored for an {@code enum} type.
+ *
+ * <li>in a class that is {@code Externalizable}:
+ * <ul>
+ *   <li> method declarations of {@code writeObject}, {@code
+ *   readObject}, and {@code readObjectNoData}
+ *
+ *  <li>a field declaration for {@code serialPersistentFields}
+ * </ul>
+ *
+ * While the {@code Externalizable} interface extends {@code
+ * Serializable}, the three methods and one field above are
+ * <em>not</em> used for externalizable classes.
+ *
+ * </ul>
+ *
+ * Note that serialization mechanism accesses its designated fields
+ * and methods reflectively and those fields and methods may appear
+ * otherwise unused in a {@code Serializable} class.
+ *
