Free XSD to DTD conversion utility?

I have a XSD (XML Schema) that I need to convert to a DTD. Is there a free utility or simple way to accomplish this? A XSLT for example? Python scripts are welcome too.

Note: this is the opposite direction of the question Free DTD to XSD conversion utility?

I am aware that the conversion may lose information…

I tried XMLSpy or oXygenXML, but it is not free and I don't have the possibility to customize the conversion.
