  1. make known to the customer this transaction ID

  2. Generate (but still NOT sending) the relevant certificate
  
  3. (JavaScript) implement the Pay button for the sole Taler way.
  Actually, this button's duty is just to ask for the (already generated)
  certificate.

  4. (JavaScript) request the certificate associated with this
  ID, through "GET /certal/"
