Switcher Pro Schematic clarification

Other Parts Discussed in Thread: TPS40055

The Switcher Pro schematic for TPS40055 has two differences from the actual datasheet:

1. BOOST pin has a series resistor connected to the lower Mosfet drain while the datasheet indicates a series capacitor.

2. SW pin has a series capacitor connected to the switched node while the datsheet suggest a direct connection to the switched node.

Is this an error in the Switcher Pro schematic ?
