In this case, I omitted, for the sake of brevity, noting that there are many MANY formats in use, especially in specialized fields such as accounting, and that, like most anything involving culture or language, one can find nearly any variation, no matter how "strange" or "foreign" it seems to outsiders, that is actually in customary use *somewhere*. There is also a difference between "regularized" usage and formats derived by well-meaning people based on their own experience (i.e. a European might very well think first of ydm, being used to seeing the day preceding the month). However, I'm unaware of any locale where 'ydm' is a *preferred* format, any casual or specialized usage notwithstanding. Probably someone will go find one, just to prove my first paragraph. In I18N, we usually say that the answer to any question begins with the phrase "well, it depends..." Finally, if one is reading standards, it behooves one to understand the customs and language adopted there. Date formats such as this are one such example, just as certain English words have special meaning in a standards context. The use of a well-known, unambiguous format, such as ISO 8601-derived dates, is sensible as such a standard as it is generally inoffensive, language/culture neutral, and recognizable.
