Thank you for the suggestions, Bastien. There is technically no need for 
regex, as all the forms are spelled out to avoid the need to create ad 
hoc regex rules for each term. Now that I think about it, the principle 
is the same as Citeproc's: a tagged inline element will be matched 
against a lookup table and replaced. I will look at the citeproc code to 
see if it leads anywhere or if it could be reused in anyway.
