Dale, Paul, thank you for the comments. I am already working on the 10-th version, to incorporate your comments. It may take some time because I am very busy till the end of this year. Maybe I will come back with questions if I have problems with the comments. Please let me know what you think about following changes I did for the 10-th version: - I moved the "Requirements Language" section to further down. It has the number 1.4. - I changed the titles according to Dale's comment and capitalized all important words. I left words within <...> and "alert" witout capital letter, excepting when they are at the beginning if a title or of a sentance. Thank you Laura 2013/11/21 Paul Kyzivat <pkyzivat@alum.mit.edu> > On 11/20/13 11:44 AM, Dale R.
