Well, if anything the converter shows how hard it is to understand the franken-templates. You've got parameters inside if parserfunctions inside parameters inside templates inside links. The second problem in the other template is with the original template. The "br" tag hasn't been  closed  ( →  ) properly.

The thing about franken-templates is that it they will accept any garbage at all regardless of whether it is accurate or not. People take advantage of this to write complex code and test it until it seems to work properly.

The markup draft generator can still be improved, but it can't magically guess what people wanted to do when there are syntax errors in the code.
