29   * Wraps a {@link ValidatorFactory} to provide caching services for the generated validator lists.
30   * This isn't normally necessary, as the validator bindings are cached along with the pages, but
31   * we're not using validator bindings because we need the validation lists to be built dynamically.
32   * It also adds "inherent" validators to the generated lists -- these are validators that are inherent
33   * to the property type.
