Deep dives
XML is better than YAML
XML is a more appropriate choice for situations that require extensible markup language and structured documents. It is suitable for annotating verses in a book, adding subtitles, and configuring complex systems. YAML, on the other hand, often leads to issues and can be error-prone, as demonstrated in cases like misinterpreting version numbers. Alternative formats like TOML or custom languages, with JSON as an underlying canonical format, should be considered for better readability and maintainability.
