purchase cost

In some ways, purchase cost is similar to the already-extant usage clause hierarchy, which includes restricted and unrestricted usage. However, a usage limitation is not necessarily due to whether or not something costs money: even if the usage is academic only, it could still be either free or non-free. A license could have multiple usage clauses, e.g. academic only when free, and unrestricted if a fee is paid. Purchase cost was created which, together with a usage clause, defines both limitations and cost.
