Hi Lucian,

My apologies for the delay in replying. InputFormatToMathML does
require a real domIDocument*, as this is used to generate the output
domIElement*; domIElements must be resident in a domIDocument.

If you have a domIDOMImplementation di, you should be able to use
something like

nsCOMPtr<domIDocumentType> dt;
nsCOMPtr<domIDocument> doc;
nsCString model("model"), none("");
rv = di->CreateDocumentType(model, none, none, getter_AddRefs(dt));
rv = di->CreateDocument(none, model, dt, getter_AddRefs(doc));

You can get a domIDOMImplementation object from (for example)
cellml_apiICellMLBootstrap::DomImplementation

Best Regards,
Justin.
