Thanks! That was the information I needed to get InputFormatToMathML to
work.

However, now I'm stuck trying to add that math to a CellMLComponent. I
tried upcasting the resulting domIElement to a mathml_domIMathMLElement,
so I could use 'AddMath', but there was no interface to do so:

nsCOMPtr<domIElement> mathml;
nsCString formstring = ToNSCString(formula);
MathMLInputServices mmlis;
rv = mmlis.InputFormatToMathML(doc, formstring, getter_AddRefs(mathml));
nsCOMPtr<mathml_domIMathMLElement> recast_mathml;
rv = mathml->QueryInterface(recast_mathml->GetIID(),
getter_AddRefs(recast_mathml));
NS_ENSURE_SUCCESS(rv, false);
rv = upcast_cmlcomp->AddMath(recast_mathml);

So, is there some other way to either a) turn a domIElement into a
mathml_domIMathMLElement, or b) add a domIElement to a
cellml_apiICellMLComponent?

I also have a more theoretical question--I created a 'Model' with a
Bootstrap thingy, and then created a new 'domIDocument' with the same
bootstrap so that InputFormatToMathML would work (as explained below).
But is there a domIDocument that it created already for the 'Model'? And
if so, can I get it? *Should* I get it? I'm not sure why I would want to
or not.

Thanks again!
