(By Alena Witzlack-Makarevich): "Marking strategies of core participants include both marking by indexing and by flagging (i.e. case or adposition marking). Variations in marking strategies include both variations in the alignment patterns and variations in position (e.g. suffixing vs. prefixing) in case of indexes. Mere differences in forms of the indexes triggered by various conjugation classes are not sufficient for a 1. This question includes cases referred to as person-based (alignment) split and hierarchical alignment in the literature."
