Other tags are treated like div.

Html Parser
In v3, the parsing of the Html relies on AngleSharp package, which follows the W3C specifications and actively supports Html5.
In v1 and v2, the parsing of the Html was done using a custom Regex-based enumerator and was more flexible, but leaving a complex code, hard to maintain.
Open MS Word or Apple Pages and design your expected output. Save as a DOCX file, then rename as a ZIP. Extract the content and inspect those files:
document.xml, numbering.xml (for list) and styles.xml.
