What's "compression"?  It taxes my understanding that the EFC
can handle arbitrary binary data except that it balks at that
which is "created using compression".  Are there other restrictions
on binary data?

Or does it simply mean to aver that data compressed subsequent
to encryption can not be decrypted prior to decompression?
