This being a presentation issue, it is in the realm of CSS.
There has definitely been discussion in the CSS working group about giving
authors the ability to control the display of numbers, times, and dates.
Most of the ideas involved the 'content' property, as in:
output#cashregister { content: sprintf('%.2d', attr(#text)) }
...which would take the contents of the element, and parse them as a
number, and format them according to the sprintf function's "%.2d"
specifier. (This is just a sample syntax I just made up and doesn't
necessarily represent what will end up in the spec, if anything.)
I haven't seen any formal proposals yet, though.
I recommend raising this issue on the www-style at w3.org mailing list.
Cheers,
