PropertyDefinition :: supressEmpty - NOT_EMPTY option

For properties the option defines a constraint, which prohibits storing instances containing empty property values in properties. When setting this options for an attribute, empty attribute values in this attribute will cause an error.

When setting this option for a collection (reference or relationship) will cause denying of storing the instance as long as the collection does not contain at least one instance.

Also when defining dynamic attribute definitions (attribute extensions), this option may be passed by the application.
