+ A compilation of the Document or its derivatives with other separate and

+ from the compilation is not used to limit the legal rights of the

+ Translation is considered a kind of modification, so you may distribute

+ their copyright holders, but you may include translations of some or all
+ Invariant Sections in addition to the original versions of these Invariant

+ disagreement between the translation and the original version of this
