      * These five API Constants are special.
      * o {@link s2Member\API_Constants\S2MEMBER_VALUE_FOR_PP_INV}

      * o {@link s2Member\API_Constants\S2MEMBER_CURRENT_USER_VALUE_FOR_PP_OS1}
      *
      * They are used by the PayPal Button Generator for s2Member.
      *
      * The `INV` value can be used to auto-fill the `invoice` for PayPal Button Codes, with a unique Code~IP combination.
      * However, in cases where multiple Buttons are displayed on the same page, the alternative {@link s2Member\API_Functions\s2member_value_for_pp_inv()} function should be used instead.
      *
      * The `ON0/OS0` values, are how s2Member identifies an existing Member *(and/or a Free Subscriber)*, who is already logged-in
      * when they click a PayPal Modification Button that was generated for you by s2Member's Button Generator.
      *
      * Instead of forcing a Member *(and/or a Free Subscriber)* to re-register for a new account,
      * s2Member can identify their existing account, and update it; according to the modified terms in your Button Code.
      * These three Button Code parameters: `on0`, `os0`, `modify`, work together in harmony. If you're using the Shortcode Format for PayPal Buttons,
      * you won't even see these, because they're added internally by the Shortcode processor.
      *
      * The `ON1/OS1` values, are used by s2Member to identify a Customer's IP Address through IPN communications with PayPal.
      *
      * Anyway, these five API Constants are just documented here for clarity;
      * you probably won't use any of these directly; the Button Generator pops them in.
