> Vendors have their own extensions to various XML metadata elements and it is desirable for these to be usable with annotations. @PersistenceCapable, @Persistent, @Sequence offer these, but many others don't. The principal ones being
> @Join, @Element, @Key, @Value, @DatastoreIdentity, @Column, @Version,
> and they need the following adding
>     /** Vendor extensions for this member.
>      * @return the vendor extensions
>      */
>     Extension[] extensions() default {};
