Yes a starting point joely as over the years the Demands list has served as a sort of an example of rules and demands , a database of items to draw upon and work from.Frankly I can not envision a "one list fits all" or universal set of rules that would accomodate all such relationships.As Sir_Russel has shown us with his sharing of his list of rules it takes some thought,negotiation and sensitivity to individual circumstances in order to render a workeable set of rules.
