Nested IRRE elements are not removed
Imagine a nested IRRE structure like Hotel->Offer->Price (taken form EXT:irre_tutorial) in the live workspace. Now the whole structure from the parent record including all child records is deleted on a custom workspace. Publishing the delete placeholders does not work for child records, only the parent gets removed and the children stay...
Since the parent record gets processed first, the "delete" action during publishing is forwared to all child records, but without the accordant publishing context. Thus, for removals it is now to be checked whether the record is marked to be removed and would be processed in the same publishing request, but just later.
How to test
Use the SVN Trunk version of EXT:irre_tutorial and run the 1nff/1nCSV tests (especially "areParentAndChildRecordsRemovedOnPublishingDeleteAction" test)
