Again, I'm wondering if you know what kind of data structure you want the
equation content to wind up in. Is it also something piece-table-like, so
that you can reuse all the I/O and undo/redo mechanisms?

If it's something else entirely, then we probably want to widen the APIs
between the document and the impexp classes so you can see your tags too.

As a useful thought exercise, you might also want to think where to draw the
API boundary line for converting from other equation formats to the MathML
format you'd be using internally.

For example, for each equation, would the Word importer be generating a
single blob of MathML output which needs to be parsed, or would it be making
more specific calls to populate something more like a MathML tree?

Presumably, a narrower API would be better, but I have no idea what it
should look like.
