The question of "order" is separate from that of a "type". In relational
databases, each returned row can be seen as an instance of a type (a la C.
J. Date), but the components of that type form a set, not a list.
Maybe you could view an element as being instances of two types at the same
time: the type defined by the attribute set and the type defined by the
non-attribute content. What a wierd thought!
