• Propose requirement with title  'Basic SW Engineering basic principles - implementation encapsulation, seperation of policies, construction by composition, don't re-invent new mechanisms when some existing'

Etienne Urbah's position on 2010-04-07

• This requirement is clear and sensible
• Correct typo 'seperation' --> 'separation'
• In order to ease the work of the software engineers implementing the Execution Service, we should just care that when using construction by composition, the specifications clearly describe the parts of external dependencies that have to be taken into account, and even copy those parts verbatim as chapters inside the Appendix (see NF9)
• Anyway, I vote FOR this requirement
