Yes, fenced blocks is what I meant. Recreating parts of xml and cdata seems the common end goal. I think we have enough modern processing that you can do looser grammars. Composition is an odd goal to me. Most notebook usage is exploratory. As such, taking effort to reuse notebooks feels counter to the benefits of doing it again that you can get. Though, I'm a fan of seeing different workflows. And excited to be shown places I'm wrong! Kudos!
