RE: Document default math properties

More general than an HTML comment (which would require preprocessing to work), how about using an initial <math/> to provide document properties in any document format. For example,

        <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" differential-d-style=”italic” | “upright” | “open-slant”>/>

As a <math/> entity, it can be used to contain default document properties. I can get this to work for OfficeMath pretty easily. It requires that the MathML reader acquire state either in itself or in its parent. For OfficeMath, the state would be in the parent since that’s where it’s been all along.

Thanks,
Murray

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?
