Notes:

Weak form of "needs". <br/><br/>When used in a FeatureLink: if the FeatureLink's start feature S is selected, then usually(!) also its end feature E must be selected. You can select S without E but you should have a good reason to do so. Always unidirectional.<br/><br/>

Weak form of "excludes".<br/><br/>When used in a FeatureLink: the FeatureLink's start feature S and its end feature E must usually(!) not be selected in a single configuration. You can select S together with E but you should have a good reason to do so. Always bidirectional.<br/><br/>
