HomHi William,
I forwarder this conversation to David and he confirmed that `<mi
mathvariant="...">` should be used,
not `<mathstyle>` as I said earlier.

David is on vacation, but promised to take a look at this issue later.
In my opinion, it would be hard to support such markup
in tex4ht, because it would generate something like `<mi
mathvariant="bold"><mo>Hom</mo>(X,Y)</mi>`, which is invalid mathml.
Some TeX wizardy would be needed to put `<mi>` elements only around
actual text and not around child math, like in the `\operatorname`.
