Notes
These are internal notes that are usually not exported and only visible to team members with write access.
But this is not a safe place to store sensible information. It is just a convenience for the reader to not be bothered with notes stored here for the authors for later use. The security level is about suppressing the representation by a CSS style. Therefore consider this as a convenience for the reader, not as a security tool.
References
For a document the references section contains pointers to resources that prove the statements of the document.
Often these proofs are not easily distinguishable from further information. In this case you may want to skip the reference section in favour for the resource list.
Resources
The resources section provides references to further information to the topic of the document.
This may be information on the internet provided by the resource or information in the team's information systems. Anything the reader of the resource might want to know, may be listed here.
