will be helpful for those in need My short answer is yes, you can include something in a sequence diagram which doesn't appear in any class diagrams.
My long answer is: making UML diagrams is not modeling, it's a way of illustrating how you plan to model; it's a tool for communicating ideas. A comprehensive, complete set of UML diagrams probably won't translate into a working system which meets your customer's needs, because while the system is being built your customer is very likely to change their mind about what they want, and you're very likely to discover things you didn't know up front which force some of your carefully-diagrammed plans to change.
