Thus your > AW quote should be i don't quite agree. there are certainly schools that would like to bann numbers in a context like this but even if you spell out all such number as text you still have the problem that you have to allow textual number, or are you really proposing that a reference to a page or a figure or heading has to be as "see figure seven.three"? and depending on the design such number might get quite a different treatment to those being part of a math formula (eg they might be in old style or they might be in the text font family or ...) so there are "textual digits" and there are "mathematical digits". frank
