'The trade id of the parent trade for N-level allocations. This element is only used to model N-level allocations in which the trade acts as block and allocated trade at the same time.This basically means the ability to allocate a block trade to multiple allocation trades, and then allocate these in turn to other allocation trades (and so on if desired).'
