HTML5's rich feature set and cross-device compatibility have rendered separate mobile-specific languages like WML, C-HTML, and XHTML Basic unnecessary.
Today, HTML5 provides a unified platform for creating websites that work across all devices, making XHTML Basic largely irrelevant in modern web development.
These changes aimed to refine how XHTML Basic interacts with modern networking environments, enhancing compatibility with newer handheld devices and browsers that now more frequently rely on HTML5.
While XHTML Basic remains functional, it is considered outdated in comparison to modern HTML5, which has become the dominant standard for mobile-first design.
XHTML-Print, which became a W3C Recommendation in September 2006, is a specialized version of XHTML Basic designed for documents printed from information appliances to low-end printers.
