I know it can be done. But see how complex it can be, when composing for 
example HTML pages.
For example see this French Wikipédia page about the Roman numeration 
systems:
http://fr.wikipedia.org/wiki/Num%C3%A9ration_romaine
(see the section 6, named "Extensions classiques")
The rulings can be drawn and rendered using HTML only, without images, but 
there are lots of CSS tricks to do that, and the page is not accessible. In 
addition the page uses only Latin letters due to the many defects in common 
fonts about Roman numerals (so the LATIN LETTER OPEN O is used as a good 
emulation instead of the turned C which does not exist as such in the Latin 
script).
And I did not see any working way to render the stretched M variant...
(Note: all the text on that page is originally not mine, although I tried to 
compose the missing characters using those CSS tricks, so the content may 
still need review).
