wanderson · 03-04-2025, 10:25 AM

I'm editing a equation-heavy epub and I'm using a lot of MathML markups. I'd like for the text to be as economical as possible, so I'd like to avoid this kind of tag:

Code:

<math xmlns="http://www.w3.org/1998/Math/MathML"> ... </math>

and instead use a single namespace declaration in the stylesheet.css, namely:

Code:

@namespace math url(http://www.w3.org/1998/Math/MathML);

which would (theoretically) enable a simpler MathML tag:

Code:

<math> ... </math>

This doesn't seem to be working for me in the Calibre editor / previewer. It may be the case that the namespace is conveyed to the first instance of a <math> tag in a file, but the remaining tags "forget" the namespace designation.

What am I doing wrong? Thanks in advance for any help.
