Hi Brian, The examples look good and I think we should use style 1 or 3.   1 would be more familiar since it mimics MS.   3 is nice and compact, but it may cause confusion -- "Where's the R bit?"  (It shouldn't, but it might.)

I don't know what is best suited for this particular document, especially considering it in the context of other PWG binding specs, the Microsoft documents, and thinking ahead, compatibility with an NEA/TNC binding spec. </tt> <tt>Attached is an example of one attribute presented in different styles for your consideration. </tt> <tt>Choice #1 is the most consistent with MS-SOH, but it is somewhat more compact than what MS does. Choice #2 is a variation on that theme, showing the positions of bits in bit-fields. Choice #3 is the most compact, because it embeds values into the diagram where it is practical to do so. Choice #4 -- there isn't one, but if you have suggestions or other examples, I'm open... </tt> <tt>I don't really care what we choose, but I think that #2 could be a problem for long bit-fields. Choice #1 is a safe choice if we're considering style compatibility with MS, but I also like the compactness and conciseness of Choice #3. </tt> <tt>Please look at the attachment and send me some feedback, or discuss on the mailing list if that is appropriate. </tt> <tt>Thanks, </tt> <tt>-- Regards, Brian Smithson PM, Security Research PMP, CISSP, CISA, ISO 27000 PA Advanced Imaging and Network Technologies Ricoh Americas Corporation (408)346-4435 </tt> [attachment "style-choices.doc" deleted by Dave Whitehead/Lex/Lexmark]
