[issue:content] draft 07, sect2.2.2, line 517, Explain the 3 types of contracts in more detail

["Chiusano Joseph" <chiusano_joseph@bah.com>]

<current>

Line 517 states "While there may be many kinds of contract, we envisage three main kinds of contract that may apply in service oriented architectures: the contracts that represent the valid use and provision of services, the contracts that represent the permitted uses of services and the contracts that result from using services.". The reader would probably expect an explanation of each of these types of contracts to immediately follow. Instead, the next paragraph discusses service descriptions (and also redefines "service interface" unnecessarily, as it was defined earlier) with no explicit association to the contract types. The paragraph that follows discusses valid and permitted uses of services - but the third type of contract ("the contracts that result from using services") does not seem to be discussed.
