Incomplete ADF Documentation...?

I am working on a application that parses atlas_doc_format representation of Confluence pages. And the only documentation that I can find is this and its schema here.

So, I followed the documentation and implemented a parser. I only noticed it when my application failed to parse the Confluence page content that there are many other types of Nodes and Marks that the documentation didn’t even mention. For example taskList, decisionList etc.

But I can find those in the schema. Is the documentation is not up-to-date…? Shall I use the schema for reference…? And is there any other types of Nodes & Marks that wasn’t listed in documentation and schema…?
