Use a default. The Jibx <value> tag takes an default= attribute. This is only allowed on optional values (like you have) and if the optional value is missing, the corresponding set-method is called with the default. If you have the default attribute set to "missing" or some other out of bounds value, the Set-method now knows when to leave the value alone, and when to update it.
