> Often, it's desirable to exclude certain fields from the optimistic locking computation.
For example, if a PurchaseOrder's lastUpdatedDate field is updated every time a line item
is added, it may be acceptable to simply use the latest value instead of requiring an optimistic
lock check / collision.
> Let's add support for such fields.
