On your example further down and on ODF shortcomings:
I am not sure these deletions should be stored as a list item at all. I
think that we should store a list-item only if the whole list item is
deleted.
Perhaps a way to handle them in current ODF is to store each of them as a
different deletion region with the <text:change> tags inside each
<list-item>.

Subject: Change Tracking of Lists - Storing delete fragments<br>
To: <a href="mailto:office-comment@lists.oasis-open.org">office-comment@lists.oasis-open.org</a><br>

Hi,<br>
<br>
I'm currently implementing ODF change tracking in KWord, and there<br>
doesn't seem to be a way to store delete changes in lists in a ODF<br>
complaint way for some scenarios. For example, if we have a list like<br>
this<br>
<br>
1. This is a list-item-1<br>
2. This is a list-item-2<br>
3. This is a list-item-3<br>
4. This is a list-item-4<br>
<br>
And we delete the second-half of the first list-item and the first<br>
half of the second list-item<br>
<br>
1. This is a list-item-1<br>
-----------------<br>
2. This is a list-item-2<br>
-------------<br>
3. This is a list-item-3<br>
4. This is a list-item-4<br>
<br>
If I were to follow the ODF delete change loading rules, we should<br>
have a delete fragment which looks like this<br>
<br>
<p>a list-item-1</p></list-item><list-item><p>This is \
a</p><br> <br>
However, such a fragment would result in a invalid XML file and<br>
consequently an invalid ODF File.<br>
<br>
The KWord approach to solving this problem is that we store the delete<br>
fragment like this<br>
<br>
<list xml:id="list1"><list-item \
xml:id="list-item1"><p>a<br> \
list-item-1</p></list-item><list-item>This is \
a</list-item></list><br> <br>
and use the RDF metadata to specify that "list1" and \
"list-item-1" are<br> not to be considered as a valid list and list-item \
respectively. So<br> while loading this delete-change, on encountering a list or \
a<br> list-item, we check whether it is a valid list or list-item and if<br>
they are not valid we merge the delete change into the current list<br>
and list-item respectively. This solution is very robust in handling<br>
any type of list-delete changes ( There are multiple other scenarios<br>
with similar problems that I haven't illustrated in this mail ).<br>
<br>
We would like to see this problem addressed in the spec, so that we<br>
can have a inter-operable way to do this.<br>
<br>
Thanks,<br>
Ganesh<br>
