[RECOMMENDED, one]

Technical Definition:

How the behaviours, requests and the Service Genre are combined to provide the functionality. What are the constraints in sequencing behaviours and requests (both of this Service Genre itself and the interactions of this Service Genre with others)? How do they interact? What are the use patterns? The pre- and post-conditions and specification of side effects and state changes are sufficient to deduce this information for a single Service Genre; this separate description combines the disparate and disconnected behaviours into a more comprehensive presentation needed to understand how to use the Service Genre either alone, or in combination with other Service Genres. This is a precise technical description; it details conforming and non-conforming interactions that span multiple requests.

Commentary:

A precise, technical explanation of how the Requests & Behaviours combine to produce the desired functions, including any constraints on the sequencing of Requests and Behaviours that govern how the Service Genre can be used either by itself or in combination with other Service Genres.
