Here are the commands in itex2MML that are "MI" (normal mi) and "MIB" 
(mi with 'movablelimits'):
http://golem.ph.utexas.edu/~distler/code/itexToMML/view/head:/itex-src/itex2MML.l#L210

There is a potential issue that the <mi> / <mo> use will be inconsistent 
and that many new operators will be necessary (or the generators would 
have to set the lspace/rspace explicitly).

I think MathJax used to generate <mo> for "sin", "cos" etc but this was 
changed to an <mi> when an explicit "Apply Function" was added:

<math><mi>sin</mi><mo>&#x2061;</mo><mi>x</mi></math>

(Having <mo>sin</mo><mo>&#x2061;</mo><mi>x</mi> won't make much sense...)

So the question is really if "max" is a function like \sin or a prefix 
operator like \sum...
