Rather difficult to have legal problems with the PEP copyright notice that always states "This document has been placed in the public domain.", or is that tempting fate? :)
According to the Creative Commons legal department, it is not always possible to attribute a work into the public domain. You can say it is public domain, but it isn't, it's still copyrighted, and even if you never enforce it, your heirs might.
