The XML serialization of HTML5, aka ‘XHTML5’

Read Original

This article provides a detailed, technical explanation of how to convert HTML5 documents into XHTML5 (HTML5's XML serialization). It outlines the three key requirements: using the correct MIME type (application/xhtml+xml), optionally using an uppercase DOCTYPE, and specifying the XML namespace. The author includes code examples, highlights browser compatibility issues, and warns of the strict error handling in XML mode, ultimately advising against using XHTML5 without a specific need.
