Re: data-* attributes

It’s not just the W3C validator. We found a similar issue with the Design Science MathFlow integration into oxygen XML 15 earlier this year at Pearson School.

We solved the issue by moving the data-* attr. Out of the MathML.

Hi www-math,

I've recently noticed that the W3C validator<> considers  HTML5 documents with data-* attributes on MathML elements invalid.

I'm wondering if this is a bug.

It also made me wonder in how far the MathML spec could adopt data-* in general. The spec suggests<> namespacing for unspecified data. When working in both XML and HTML5 contexts this seems less than ideal.

Best regards,
