I was looking at the htmlized ASCII rather than the HTML.

Now I look at the XML, I see you've tried to emulate the .svg's with the 
ascii-art alternatives.
I think I would have not bothered, and instead just pasted the original 
equations from RFC8312 into the ascii-art alternatives. But as I said, 
that's my personal preference (and at least Rod agrees). It would also 
allow a good diff between the ASCII versions to see if any of the maths 
had changed (which BTW would have highlighted the flip of the exponents).

No great biggie for me. Especially now I know that I (and others) have 
the HTML.

However, I don't seem to be able to copy/paste the svg's at all from the 
HTML, which is what I was originally trying to do with the ASCII art, 
which was what led to my whinge.
