Marks a property as being excluded from history.


This means the property values are not maintained in the history table. Typically this
would be placed on relatively large properties (Clobs, Blobs, large varchar columns etc)
that are considered not interesting enough to maintain history on excluding them reduces
underlying database costs.




When placed on a ManyToMany this means that the intersection table does not have history
support.
