I think I would respond differently to Avram's question: the subtag '1995' (usw), however, would have a restricted meaning and could not be reused for other purposes. In that case it could only mean a variation of the 'iso9' subtag. While taggers could use the variants arbitrarily to form tags, the meaning associated with those variants is not variable. Multiple meanings cannot be assigned to a subtag.
Besides, I think it would also be odd to require using two subtags when only one is really necessary, as the subtag "iso9" would have no specific meaning without an associated year subtag.

That's a really ugly subtag. However, it would work and is valid. Perhaps "1995iso9"?
