Math Editor Implementation Questions

    I'm working on a sort of mini Label Editor for my own purposes and
because I need super and subscripting capabilities ( and maybe fractions) I
decided to settle on (a subset of) MathMl as my model.
    Everything was going pretty well until I added styles to the mix. My
style element itself works fine but figuring out how to actually edit it is
turning into a real pain. In a sense the style element is a bit different to
the others because it can be split etc. depending on the current selection.
You can end up with two styles the same next to each other, which really
should be combined - and if they only contain text then the text elements
should also be combined to make a single text element. Various other
complicated situations also arise!

    The simplest thing to do of course is to just leave the styles in, but
they soon overwhelm the whole structure, with a large number of redundant
style elements.

    My current implementation for clearing out the redundant styles nearly
works but it is so complicated that I dont have any real confidence that it
will ever be bug free so I have decided to reimplement the whole thing.
Before I do however I thought I'd see if anyone has some suggestions on the
best way to do this.

Any help would be greatly appreciated!
