Ok. The original copyright owner of A gave me the rights to use A, so I 
used A for producing B (also a mere "copy"), and then I'm the copyright 
owner of B because I'm the author of B. Then automatically by law (Berne 
Convention) I have all the rights on B, and I can decide to license B 
under my terms of choice.

I can use A in B, only if I respect the license of A. So in case of BSD 
and ISC only if I cite the original authors, and the original license. 
So very minimal requirements.

Put in these term it seems very simple.

Ok obvious. A remains A. I owns only B.
