I'm not sure what you mean here. In German (EU?) law such a collection 
can have it's own protection *as a whole*, regardless of and not 
affecting the original protection or rights on its components.

Then the PD parts, and whatever else has been added from third parties, 
can be pulled out of the collection by everybody, and can be used at the 
original conditions applicable to every single part.

The Win-SDK part of older Delphi Help is such a part, whose rightholder 
still is Microsoft. It can be assumed that Borland has obtained the 
right to distribute these files, otherwise they had not been allowed to 
do so.
