The statement about the C560XL (Excel) being separate from the C500/550/560 is not completely correct. If you have the C500/550/560 type rating you only need to complete differences training and possibly (depending on your CAA) a checkride in the 560XL to be able to operate it.
There is a company in sweden (I belive - Malmo!?), Inter Air, who operates Ciatations and that, I have been told, is the way they do it.
