1. A decoder for reconstructing an array of information samples from a data stream, the array of information samples representing a spatially sampled information signal, which is using a hierarchy level order from lower hierarchy level to higher hierarchy level, recursively partitioned into secondary leaf regions of different sizes by a spatial multi-tree subdivision which forms a secondary sub-division of primary leaf regions of a primary multi-tree sub-division, wherein the decoder includes a processor and is configured to:
extract and check, for regions corresponding to any of an inheritance set of at least one hierarchy level of the spatial multitree subdivision, which are composed of a corresponding set of secondary leaf regions, and using the hierarchy level order, an associated inheritance flag from the data stream, as to whether the respective inheritance flag prescribes inheritance or not;
for each region for which the associated inheritance flag prescribes inheritance,
copy an inheritance subset including at least one syntax element of a predetermined syntax element type which is contained in the data stream for the respective region for which the associated inheritance flag prescribes inheritance, into, or use the inheritance subset as a prediction for, a corresponding inheritance subset of syntax elements representing coding parameters associated with the secondary leaf regions which the respective region for which the associated inheritance flag prescribes inheritance, is composed of, and
suppress extraction and check of further inheritance flags for the secondary leaf regions which the respective region for which the associated inheritance flag prescribes inheritance, is composed of.
