TODOs for MathML <a> element #340
Description
TODOs:
- Update the MathML full spec to allow a elements outside of an HTML context.
- Rename all mrow sections the MathML core spec to mrow / a
- Discuss the usage of a elements without href attribute in the spec. (Should that be encouraged or discouraged?)
- Decide if href will be entirely removed from MathML full
- Develop tests for the MathML specific attributes of the

About the tests, @tannal mentioned this to me this morning and
https://wpt.fyi/results/mathml/relations/css-styling/attribute-mapping-001.html
https://wpt.fyi/results/mathml/relations/css-styling/attribute-mapping-002.html
cover the mapping of these attributes to CSS on the
<a>element. Probably, we can add more specific tests to check observable behaviors though when<a>is used though.eerii commentedon Sep 29, 2026
relations/css-styling/attribute-mapping-*.htmliterate MathMLFragments, which includesa. So any tests using it are already testing it. Then, link behaviour and IDL is already covered by theanchor-*,a-*andhref-*tests inrelations/html5-treethat fred, luke and tannal made.We were missing some observable behaviour reftests for the MathML attributes of
a. I made PR web-platform-tests/wpt#63056 that coversmathcolor,mathbackground,mathsizeanddisplaystyle.mathml: Add tests for MathML style attributes on the <a> element

In the meeting we didn’t fully understand what would happen if a MathML generator would replace all mrow elements with a elements regardless if they contained the href attribute.
As a software developer it would be more effective to use only a as this would make the source code shorter and the output (regarded as string) shorter.
