The ceiling can be used as a diffuser, and there are diffusers that clip onto the flash or fit over the head. The 540 also has a mini bounce card and diffuser built in. But I use a Sto-Fen Omni-Bounce most of the time for any work where I'm closer than 15 feet or so. http://www.bhphotovideo.com/c/product/160596-REG/Sto_Fen_OM_MZ40_OM_MZ40_Omni_Bounce.html
I also use a fong lumisphere on occasion. It provides more diffusion than the omni-bounce but also kills more light. As I mentioned in a previous post, when in daylight, you'll almost always have to use high-speed synch to get a good exposure, and you have to take care that the camera doesn't revert to 1/180th shutter speed when you turn the flash on.
