Accessibility guidelines and requirements
It is Microsoft policy that all content be accessible. Compliance with the Microsoft Corporate Accessibility Policy is achieved by ensuring that content meets the necessary Microsoft Accessibility Standard (MAS) requirements. MAS contains a compilation of national and international standards and regulations that affect all components of software and hardware development, including web content and multimedia. It also includes information about implementing and testing each standard.
