An attribute-value system is distinguished from a simple `` feature list '' representation in that each feature in an attribute-value system may possess a range of values ( e.g. , feature formula_1 below , which has domain of { 0,1,2 } ) , rather than simply being `` present '' or `` absent '' . Other terms used for `` attribute-value system '' .
