There does not seem to be any real support for vulgar fractions in  
MathML (neither as specified nor as currently implemented).  I agree  
that adding such support to MathML might make more sense than adding  
another way of encoding fractions to HTML proper, though, — *if* mark- 
up is needed — despite limited use of vulgar fractions in mathematics.

I have not approached any browser makers yet, and I am not aware of  
any good reason for not supporting the fraction slash. Now, you are  
obviously aware of the issue and presumably in a situation to follow  
it up. Let me know if there is anything I can do to make it more  
likely for this feature to be considered for addition to Firefox  
(apart from actually implementing it myself).
