The author of nom is too busy to review the PR, and cargo does not allow for git dependencies, so I am going to copy my implementation into this code base so I can use upstream nom so I can push to cargo. While this code has been submitted upstream to nom which is under the MIT license, I am the author of this code so I believe I have the full right to also release it in this project under the 0BSD license.
The body element is re-used as a child element in blocks, so it makes more sense to make a function that renders that as opposed to a function that renders a top-level-only container that contains only a body.
