Members inherited from Feature (38 members)

	`basic_feature`	`R`	The `last_chaining_feature` if one exists, otherwise this `Feature`.
	`cross_feature`	`R`	The second `chaining_feature` of the `crossed_feature` of the `owned_cross_subsetting` of this `Feature`, if it has one. Semantically, the values of the `cross_feature` of an end `Feature` must include all values of the end `Feature` obtained when navigating from values of the other end `Features` of the same `owning_type`.
	`direction`	`RW`	Indicates how values of this `Feature` are determined or used (as specified for the `FeatureDirectionKind`).

	`is_composite`	`RW`	Whether the `Feature` is a composite `feature` of its `featuring_type`. If so, the values of the `Feature` cannot exist after its featuring instance no longer does.

If the `owning_type` has n end `Features`, then the multiplicity, ordering, and uniqueness declared for the `cross_feature` of any one of these end `Features` constrains the cardinality, ordering, and uniqueness of the collection of values of that `Feature` reached by navigation when the values of the other n-1 end `Features` are held fixed.

For example, a `Classifier` might be the difference of a `Classifier` for people and another for people of a particular nationality, leaving people who are not of that nationality. Similarly, a feature of people might be the difference between a feature for their children and a `Classifier` for people of a particular sex, identifying their children not of that sex (because the interpretations of the children `Feature` that identify those of that sex are also interpretations of the `Classifier` for that sex).

For example, a `Classifier` might be an intersection of `Classifiers` for people of a particular sex and of a particular nationality. Similarly, a feature for people’s children of a particular sex might be the intersection of a `Feature` for their children and a `Classifier` for people of that sex (because the interpretations of the children `Feature` that identify those of that sex are also interpretations of the Classifier for that sex).

	`type_relationships`	`R`	The other type, feature relationships and `FeatureChainings` owned by this `Type`.
	`unioning_types`	`R`	The interpretations of a `Type` with `unioning_types` are asserted to be the same as those of all the `unioning_types` together, which are the `Types` derived from the `unioning_type` of the `owned_unionings` of this `Type`. For example, a `Classifier` for people might be the union of `Classifiers` for all the sexes. Similarly, a feature for people’s children might be the union of features dividing them in the same ways as people in general.

This property may be true, even if there are not actually any `owned_relationships` with `is_implied = true`, meaning that no such Relationships are actually implied for this Element. However, if it is false, then `owned_relationships` may not contain any implied Relationships. That is, either all required implied Relationships must be included, or none of them.
