well, you're an original 'roman' guy so you'll get the easy creation
question

Better to say "no", otherwise one can argue that I'm also able with Etruscan numerals
http://en.wikipedia.org/wiki/Etruscan_numerals

BTW, some linearity equations like
x = IIII - IV
can be problematic (actually {'nulla' , 'N' } are valid solutions, but it's an historical matter)
http://en.wikipedia.org/wiki/Roman_numerals

One can say that such questions should be avoided because there are no reasons for non-roman people to know about roman numerals
(at least they are the same of non-maya people to know about maya numerals), and it's generally true .

But, given that we are talking about ConTeXt and given that \romannumerals is a ConTeXt macro,
in this particular case such questions are valid.

This open the door to similar questions (cfr core-con.lua,core-con.tex for persian,thai etc)
and given that Unicode sooner or later will cover all kind of writing systems of the human race,
I expect that some day some questions will be mixed with maya numerals.
