Hi Theo: You reviewed the superposition paper for AOSD 2002. I found an earlier reference to superposition than given in the paper you reviewed. Please can you double check that @ARTICLE{dijkstra:aop, AUTHOR = "E.W. Dijkstra and C.S. Scholten", TITLE = "Termination Detection for Diffusing Computations", JOURNAL = ipl, YEAR = 1980, PAGES = "1-4", MONTH = "", VOLUME = 11, NUMBER = 1 } already talks about superposition. So did we have this form of AOP already in 1980? -- Karl Reference from: @ARTICLE{mikkonen:flexibility, AUTHOR = "Tommi Mikkonen and Peeter Pruuden", TITLE = "Flexibility as a Design Driver", JOURNAL = ieee-computer, YEAR = 2001, PAGES = "52-56", MONTH = "November", VOLUME = "" , NUMBER = "" }
