Or @ForeignKey(name="MY_FK") on the field/property.

Or @Unique(name="MY_IDX") on the field/property.

Or @Index(name="MY_IDX") on the field/property.

presumably in @Element, @Key, @Value ?
because to do that on a field/property add @ForeignKey against the 
field/property.



PS. Is it possible to get a copy of the latest spec with all updates that have
