Underspecification of ODF for change-tracking

In the past month I have stumbled over two problems that will influence
our ODF change-tracking and should therefore be fixed for ODF 1.3:

https://tools.oasis-open.org/issues/browse/OFFICE-3845
https://tools.oasis-open.org/issues/browse/OFFICE-3847

We need implementors feed-back on those.

Thanks,
