```An ordered list means there is an order, *not* that there is anything

which is the same as {3, 1, 2}.  An ordered list, like an ordered set
- (1,2,3) which is distinct from (3, 1, 2).  But a definition list is
like a mapping:
{ (1, 1), (2, 5), (3, 6) } which, in set theory, is just a subset of
{1, 2, 3} x {1, 5, 6}.```

```Apologies to those amongst you who don't "do" set theory.  It'd be
better with diagrams.  But the point is that if you want a starting
attribute in an ordered list you're actually setting up an assocation
between the number and the content of the list item.  So you need a
definition list.  Because an ordered list is just a way of defining a
relationship between the parts of the ordered list, not between the
parts of the ordered list and something outside.

`Interesting, but I don't agree :)`

```IMO list items are "1st", "2nd", "3rd" and so on, and this makes sense
as long as all list items are together, but sometimes you need to split
the list (for example when you display 10 results per page),
so then start makes sense.```

```There are some usability problems:
WAI says that document must make sense without stylesheets.
From a users point of view:
1. a
2. b
3. c
is very different from:
11. a
12. b
13. c```

```I don't think that definition list can replace that either.
<dt>11</dt><dd>Foo</dd>```

```"Foo" does not define "11".
It's just supposed to be 11th element of some list.```
