Document default math properties

Reviewing my Math in Office<https://docs.microsoft.com/en-us/archive/blogs/murrays/> blog posts, I ran into the 2010 post MathML To-Do List<https://docs.microsoft.com/en-us/archive/blogs/murrays/mathml-to-do-list>, which discusses default math properties and equation numbering. Seems we ought to be doing something about these things this time around, 10 years later. We’ve identified myriad more properties that could be set at the document level and inherited by math zones. HTML is one document format that could support default document properties perhaps as some kind of comment. I doubt that we’d be able to get the properties into CSS. OfficeMath has had default document properties from its beginning in 2007.

Thoughts?

Thanks,
