OK, after poking at this a bit and not getting very far, I moved on to
other things (and had more success there--more on that in a different
email), but now I'm back to this bit. Unfortunately, I believe the code
alan linked to, while interesting, is actually the code I'm trying to call
myself, so is a level or to too deep to be instructive for my own problem.

So, to recap: Does anyone know to do one of the following:

- convert a 'domIElement' to a 'mathml_domIMathMLElement' so I can use
AddMath
- convert a 'domIElement' to a 'cellml_apiICellMLElement' so I can use
AddElement
- add a domIElement to a cellml_apiICellMLComponent in some other way.
