25    properties handling:
26    - adding and removing will not change property count and property#
27    - the description (ParamInterface::id/name/type) of the removed property is always "?"
28    - group membership of the removed property is always 0
29    - requests for property# are redirected to the new property# or ignored
30    groups handling:
31    - group count is constant
32    - accessing group name of the removed group will return "?"
33    - removed properties are moved to group 0
