In AsciiDoc and GitHub's Markdown, admonitions (a.k.a. callouts or alerts) consist of five types (NOTE, TIP, IMPORTANT, CAUTION, and WARNING).
However, rustdoc consist only of a warning block.
Why is this? Is this an intentional limitation?
Looking at usage examples in the clap crate, I think it's also used for purposes like "NOTE" or "TIP".
