This is kind of a follow-up question to one I asked earlier. I thought that if I generalize it, it would be better to ask it separately.
I want to create a derivative work of another work, which is licensed under Creative Commons Attribution Share-Alike (CC-BY-SA). This means that I need to release my work under a license compatible with CC-BY-SA.
The problem is that in my work, I also have other elements (e.g. fonts and images), which I have no right to license.
So, is it in some way possible for me to be compatible with CC-BY-SA? For example by licensing only the parts I made under CC-BY-SA and making it clear that those other elements are not licensed under CC-BY-SA?
