+MathML core specification provides a new way to specify 
+an accessible description of mathematical expressions, using the 
+\Link[https://w3c.github.io/mathml-docs/intent-explainer/]{}{}intent attribute\EndLink.
+\LaTeX{} will provide commands to set the intent attribute for
+mathematical expressions. We can redefine these commands
+to insert the necessary attributes in the MathML output.
