Hi, In bug 1548524, I intend to deprecate XLink attributes (“href”, “type”, “show” and “actuate”) on MathML elements. This has never been supported by other browsers and AFAIK there is not any plan to do so. Gecko actually only has partial support for XLink and there is no plan to implement full support [1].
MathML3 (released 5 years ago) introduced a href attribute as a replacement for xlink:href [2]: "Note that MathML 2 had no direct support for linking, and instead followed the W3C Recommendation 'XML Linking Language' [XLink] in defining links using the xlink:href attribute. This has changed, and MathML 3 now uses an href attribute. However, particular compound document formats may specify the use of XML linking with MathML elements, so user agents that support XML linking should continue to support the use of the xlink:href attribute with MathML 3 as well. " Although MathML 3 still says xlink:href should be supported in user agents supporting XML linking, there is an open item regarding what to do in future versions [3]. We have been sending deprecation for xlink:href on MathML elements for 7 years [4] however users have reported bugs for xlink:href in the past [5] so it is sensible to be a bit more careful. For now these attributes will only be disabled in nightly and a use counter will be introduced to determine how much this feature is used.
