So, I have the following code:

nsCOMPtr<domIElement> mathml;
nsCString formstring("x = y");
MathMLInputServices mmlis;
rv = mmlis.InputFormatToMathML(NULL, formstring, getter_AddRefs(mathml));

The return code is 2147942487, which if I translate to hex, I can find is
either "NS_ERROR_ILLEGAL_VALUE" or "NS_ERROR_INVALID_ARG". *Which*
argument, it won't tell me, but I'm guessing it's the NULL.

Now, when I was translating the other way, NULL was fine:

rv = mmlis.MathMLToInputFormat(input, NULL, indent, cinfix);

but, I suppose, no longer.

Since InputFormatToMathML is from OpenCell, not the API, I don't have any
documentation at all, so I turn to you all and ask: am I right that it
requires a real 'domIDocument*'? And if so, how do I go about making one?
Do I make (I assume) a mathml_domIMathMLDocument and cast it? Is there a
mathml_domIMathMLDocument factory somewhere?
