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?

WG Notes: 5.2.1 LDPC servers must also be conformant LDPR servers. A Linked Data Platform Container must also be a conformant Linked Data Platform Resource. Also in 5.4.4 we state "The newly created LDPR could also be a LDPC, therefore servers may allow the creation of LDPCs within a LDPC." Consider updating informative section that LDPC's may contain LDPC's and LDPC's are just LDPR's.

Resolution: Added some informative content to 5.1.2 Ordering section.
