[Commentor] LC-2815 Ashok Malhotra (archived comment) [Comment] We discussed that LDPCs are a subclass of LDPRs and so containers can be members of other containers. Do we say that somewhere? I could not find such a statment. Perhaps we need to add it. Also, of a container contains other containers, how would ordering work? [Commentor reply] tocheck [Working Group decision] 
Added some informative content to 5.1.2 Ordering section.
