Problem

No content protection rule can be so good that it will not need exceptions. The user may need to interfere with content protection tags when a rule is bad or the source text is faulty etc. At the moment this can only be done, when tag errors in general are allowed. But this is not a good option.

Solution

Make it possible to explicitly "undo" the content protection in the source segment and make it thus editable as simple text again, e.g. by right-click on the tag.
