[Om] Tuple and list : any distinction?

[Joe Collins]

The OpenMath ecc CD defines Tuple and the list1 CD defines list.

Is there any essential distinction between Tuple and list?
If so, what?

Some of the definitions in list1, list2 suggest (to me) that the order of the 
list elements are arbitrary. Is this actually the case?
