It is designed so that it can be used to protect announcements which are originated by resource constrained edge routers. This has special operational considerations, see Section 6. from wikipedia, the authority for everything :) Use of the passive in English varies with writing style and field. Some publications' style sheets discourage use of the passive voice,[3] while others encourage it.[4] Although some purveyors of usage advice, including George Orwell in Politics and the English Language and William Strunk, Jr. and E. B. White in The Elements of Style, discourage use of the passive in English, its usefulness is generally recognized, particularly in cases where the patient is more important than the agent,[5] but also in some cases where it is desired to emphasize the agent. randy
