-### destroyStrategy
-By default, when a field is removed from the DOM and the $destroy event is broadcast, the schema-validate directive 
-will update the model to set the field value to undefined. This can be overridden by setting the destroyStrategy 
-on a field to one of null, empty string (""), undefined, or "retain". Any other value will be ignored and the default  
-behavior will apply. The empty string option only applies to fields that have a type of string; using the empty string 
-with other field types will just be set to the default destroyStrategy. If you'd like to set the destroyStrategy for 
-an entire form, add it to the formDefaults in the [globalOptions](#global-options)
