A formalism is motivated and described for representing defaults in specifications. The formalism is called ordered theory presentations. The ability to represent defaults narrows the gap between a customer's initial requirements and a formal specification, and supports reuse on both a small and a large scale. Issues are illustrated throughout reference to the lift example. The application of the formalism to specification revision is considered.<>
