Item 4 is important, but has 1 significant exception: If the product or individual item within product is known by design to be Poser 5 only, e.g. uses Dynamic Cloth, then and only then it should have version 5. That way the user's attention is drawn if they've picked the wrong one. Similarly if Poser AND ProPack MAT/MORs are present in the product, the ProPack-only items could have version 4.3 for similar reasons. Any discussion on where ReadScript Injection files should be stored? Some vendors are using !Daz folders, others are placing just about everywhere...
