I's prefer to see in the actual files (so you know what is the public domain content) as above but I also think it's needed somewhere top level. If not the NOTICE file or perhaps then the LICENSE file as suggested by "Attribution is required (in a similar fashion to permissive licenses)". [1] Think what you do when adding MIT/BSD licenses (ie add them to LICENSE). Take this scenario. Someone downloads the TLF repo because they want to use it in their project, they take a look at the top level LICENSE/NOTICE and currently would have no idea that there was content from the public domain in our repo, so they just bundle it up and distribute it with no changes to their LICENSE or NOTICE.
