Wed Feb 14 10:28:38 2018, comment #3: I've created a new library for make4ht, `make4ht-domfilter`. It can modify the document's DOM using Lua functions. The <mn> as well as <span> issue can be fixed using `joincharacters` filter: local domfilter = require "make4ht-domfilter" local process = domfilter {"joincharacters"} Make:match("html$", process) It can be also requested on the command line using	Michal Hoftich <michal_h21>
Thu Feb 1 23:41:42 2018, comment #2: It comes from tex4ht-mathml.tex, line 3149: \Configure{MathClass}{7}{*}{<\a:mathml mn>}{</\a:mathml mn>}{0123456789} This configuration creates template that is passed to the DVI file and tex4ht applies it to math class 7. I don't know what \Configure{FormulaClass} does, this whole business is really mysterious to me.	Michal Hoftich <michal_h21>
Thu Feb 1 23:19:49 2018, comment #1: I'm sorry, I don't understand yet. Do you know where the "<mn>" string actually gets emitted? Because "mn" only occurs as a word in a few places anywhere in the *.tex files (and not in tex4ht-c.tex), none of which looks especially relevant to the creation of the <mn>1</mn> to me. Anyway, in tex4ht-mathltx.tex, there are some \Configure commands for some, but not all, of the numerals, starting around line 2245. Only 0..6 are configured there, and only 4..5 with the "mathltx-" option (whatever that is). What happens with 7..9? Does any of this make sense to you? I wonder if Eitan provided an option for determining the behavior of the numerals in math mode. So wish he were still here ...	Karl Berry <karl>
Wed Jan 31 23:40:06 2018, original submission: User reported on TeX.sx [1] an issue with number handling in the MathML output. The issue is that $14$ produces <mn>1</mn><mn>5</mn> instead of <mn>15</mn>. The number markup is inserted by tex4ht in the DVI processing stage, so it is necessary to fix this issue in tex4ht-c.tex.
