Michael Pizzo commented on ODATA-346:
-------------------------------------

I'm okay with scoping it to annotations, both in CSDL and instance annotations. Basically saying that the order of elements in an annotation collection is significant and must be preserved by client libraries, without implying anything about persistence.

> Terms often require lists of primitive or complex values in which the order of entries is significant, e.g. when defining a leveled hierarchy for data aggregation.
> Making the order of child elements in a <Collection> element significant avoids the need of always using a complex type with a sequence property to express the order.
