reference of ICAS element sets

provided that an effective version of ICAS is established (please see AAT ICAS 9059), ICAS element sets are structured for reference by developer, element set type, and element set identifier elements. if 'ICAS' or another appropriate ICAS term is included in the developer element, then the element set reference may be represented as an 'element set' ('localization', 'term', 'character', or 'format' set). however if the developer element does not incorporate an ICAS identifier, then element set reference should be represented as an 'ICAS element set'.
