Re: [office] Enable MathML for browsers

[Francis Cave <francis@franciscave.com>]

Hi all

I tested saving CSD01 Part 4 from LO in both HTML (File - Save as) and 
XHTML (File - Export), and the <img/> elements in the HTML appear to 
have name attributes with the same values as the id attributes on 
corresponding <span> elements containing MathML expressions. I haven't 
checked this thoroughly, but the first and last MathML expressions 
correspond, and a spot-check of equations elsewhere in the spec 
correspond. So, Regina, maybe you are too pessimistic.

Kind regards,

Francis
