Re: XML Chunk Equality

/ Elliotte Rusty Harold <elharo@metalab.unc.edu> was heard to say:
| The finding states:
|
| Unordered lists (such as the [attributes] property) are compared
| pairwise but without respect to order. In other words, two unordered
| lists "A" and "B" are the same if and only if there exists a set of
| pairs of items, one from each list, such that the two items in each
| pair are equal and no item from "A" or "B" appears in more than one
| pair. It follows that they can only be the same if they are the same
| length.
|
| I don't think this is quite correct. I agree with the intent but the
| wording seems off. In particular given set (A, B, C, D) and set (1, 2,
| 3, 4) I think the set of pairs {(A, 1)} could satisfy this if A and 1
| are equal even though B, C, D do not equal any of 2, 3, 4. To fix this
| I think you need the additional constraint that every item from A and
| B appears in exactly one pair rather than " no item from "A" or "B"
| appears in more than one pair."

Indeed. Thanks.
