Hi Andreas, as far as I know there's already a consensus that for this reason the removed content has to be moved to the tracked changes section. Regards, Frank On 26.04.2011 16:19, Andreas J.

I strongly believe that this property should be retained within ODF 1.x. Unfortunately GCT makes this impossible, considering the following example from the GCT proposal (6.12.2): <text:p> How text is deleted <delta:removed-content delta:removal-change-idref= €ct2 €> or <text:span text:style= €bold €> removed</text:span> like this </delta:removed-content> from a paragraph. </text:p> An application considering delta:removed-content a foreign element would show: How text is deleted or removed like this from a paragraph. rather than How text is deleted from a paragraph.
