Right the metadata itself is project specific (that's what I meant by "payload"), but the structure of the descriptor tree might be the same, possibly allowing for re-use of code for model merges, model traversal (if there is such thing) etc. > This might help avoiding to write and maintain redundant code (e.g. > merging > > meta data from different sources) and also might be beneficial for the > sake > > of memory.
