 :For two-way compatibility, it's often the case that the stewards of both licenses must work together to remove inconsistencies between the licenses, possibly through versioning of one or both of the licenses. CC does not anticipate versioning again in the foreseeable future, but did work with the license stewards of several compatible license candidates during the 4.0 versioning process in anticipation of this process.  In cases where licenses are not actively stewarded, participation of the relevant license-user community may be sufficient. If there is no active community of licensors, the value of a compatibility determination may be small, unless there is a very large existing pool of content otherwise incompatibly licensed.

The extent to which the candidate licenses fails to license or otherwise address the other rights covered by CC licenses (e.g., sui generis database rights), or licenses additional rights beyond those in the CC license (e.g., patent rights), will be an important part of the compatibility analysis.
