Interdependent change tracking, ODF proposal

[Regina Henschel]

Hi Miklos,

How is the hierarchy of the now two child elements of 
<text:changed-region> determined? Is it the element order in markup or 
the date in their <office:change-info> child element?

What should happen if the <dc:date> of the <office:change-info> elements 
are in contrast to the type of elements? For example there is a delete 
of content that is inserted later than the delete was made? Or there is 
a formatting on a content that was already deleted according to the 
<dc:date>?

Kind regards,
Regina
