Next snippet To highlight this, a feature with such a feature value can be flagged as derived (though this is not required, nor is it required that the value of a derived feature be computed using a feature value ...) Related snippets derived – Specifies that the usage is derived. Such a feature is typically expected to have a bound value expression that completely determines its value at all times ...
