 /**
  * Support for parameterizable types. A {@link UserType} or {@link UserCollectionType}
- * may be made parameterizable by implementing this interface. Parameters for a type
- * may be set by using a nested type element for the property element in the mapping
- * file, or by defining a typedef.
+ * may be made parameterizable by implementing this interface. Arguments to parameters
+ * may be specified via {@link org.hibernate.annotations.Type#parameters}. In XML,
+ * parameters for a type may be set by using a nested type element for the property
+ * element in the mapping file, or by defining a typedef.
+ *
+ * @deprecated This interface provides little type safety, and results in verbosity
+ * at the use site. A much better approach is now provided by the possibility of
+ * declaring a {@link UserType} via an intermediate type annotation.
+ * <p>For example, we could define a type annotation for the type {@code TimePeriod}:
+ * <pre>
+ * &#64;Type(PeriodType.class) // the type itself
+ * &#64;Target({METHOD, FIELD})
+ * &#64;Retention(RUNTIME)
+ * // the type annotation:
+ * public @interface TimePeriod {
+ *     // member specifying custom configuration
+ *     // affecting the behavior of the UserType:
+ *     boolean days() default false;
+ * }
+ * </pre>
+ * <p>Then the {@code UserType} implementation receives an instance of the type annotation
+ * in its constructor:
+ * <pre>
+ * static class PeriodType implements UserType&lt;Period&gt; {
+ *    private final boolean days;
+ *
+ *    // constructor configures the UserType from
+ *    // information in the annotation instance:
+ *    PeriodType(TimePeriod timePeriod) {
+ *        days = timePeriod.days();
+ *    }
+ *    // implementation of UserType operations:
+ *    ...
+ * }
+ * </pre>
+ * <p>Therefore, use of {@code ParameterizedType} is no longer encouraged.
