* specified in @write_resource_flags, this is not done.
*
* As a further requirement, this function requires that the
- * @will_be_in_output_wim member be set on all streams in @stream_list as well
- * as any other streams not in @stream_list that will be in the output WIM file,
- * but not on any other streams in the output WIM's lookup table or sharing a
