P2SH addresses support exotic transaction outputs, bu= t not all exotic transactions. This payment protocol can allow for combinin= g multiple outputs. A PaymentRequest for sending money to multiple parties,= for example, could not fall back to a single address.

bitcoin: URI can be just bitcoin:?request=3Dhttp...
