--- Comment #4 from Nikolay Sivov bunglehead@gmail.com --- That's an unexpected use case. I don't think it would be a problem to have annotations, but using dwrite header for a typelib is not going to get very far, I suspect. Using dwrite_1.idl will already produce duplicate method names, I don't think that's allowed.
