After reading the opinions to date it looks pretty much split down the middle.
My take is that there are Business Rules and there are business rules. Business rules that determine your preconditions and postconditions for a use case should be entered into your use case. Business rules that are described by an OCL like notation should not go into your use cases, because you have not defined the attributes upon which the business rules operate yet. So why not both? Put a general description of the business rule in your use case, Precondition: The account must have a balance greater than the sum being withdrawn in order for this use case to occur. Clarify this with the OCL example, (that I am not goint to try and repeat because I have deleted the replies that pointed out all of the many mistakes that I made) in your Analysis model. You might even like to add traceability back to the use case.
