A couple of simple questions:

Can CC-BY material be incorporated into CC-BY-SA material?
Can CC-BY material be incorporated into GFDL material?

We have such compatibility from BSD or PD into GPL, and it's pretty
important in that context -- but it's not clear to me if the same
principle is applicable for these scenarios. CC-BY seems to require
that no new restrictions can be applied beyond the original licensing,
and that would seem to make the licenses incompatible. Is that
interpretation correct? If so, can this problem be solved? It seems
that at least unidirectional compatibility would be desirable.
