Beside what is outlined in the Attribution Required page, what are some potential citation formats that could be used? Think along the lines of how you would cite a question/answer in a book, blog posting, paper, etc that you are writing. Not for re-use of the contents, but to the contents.
I feel that a good format would conform in spirit to other commonly used formats such as IEEE/ACM, APA, etc. This way it would be easier to convert from your proposed style to any of the previous, should strict bibliography and reference rules apply to you work.
I've posted my suggestion below.
Please note that the purpose of the citations are not for the reproduction of content, as described on the Attribution page, but citations to the content.
