characteristic of inheres in role represented set 'Represented sets' are realized in the processes perception, design or cognition. A role inhering in the set of attributes of a mark in a relational information display that share a scale type and that convey information about another entity. There is a distinction between elements and sets. Sets are groups, or sets of elements (with cardinality of at least one). At this time we do not know if elements with different roles can exist in a set with a different name, i.e., an acribee role within a time set. It seems unlikely that this is possible. Zhang J.
