Mark van Lent: Change the workflow of a content type to "(Default)"

I had some difficulty finding out how to do this. Especially since exporting the workflow definition did not provide any clues. Here's a quick note so I won't forget it again (thanks to Maciej Zięba from STX Next).

Add the following to workflows.xml:

<bindings>
  <type type_id="File" remove="True" />
</bindings>

After reinstalling the Generic Setup profile, the specified content type (in my case File) will have the default workflow.
