Hi Jagath,
mathvariant 'double-struck' is called /blackboard bold/. There are no 'bold
double-struck', I believe.
Therefore /<mstyle mathvariant="bold">/ is redundant.
Best regards,

Hi Georg,
One of the easiest way to achieve correct MathML tag for this is to use below
tex4ht cfg on your MWE:
%-------------------------------------------------------------------
% htlatex <tex> <cfg>
\RequirePackage{amssymb} % used for \mathbb
\RequirePackage{bm} % used for \boldsymbol
\Preamble{xhtml,mathml}
\Configure{VERSION}{}
\Configure{DOCTYPE}{\HCode{<!DOCTYPE html>\Hnewline}}
\Configure{HTML}{\HCode{<html>\Hnewline}}{\HCode{\Hnewline</html>}}
\Configure{@HEAD}{}
\Configure{@HEAD}{\HCode{<meta charset="UTF-8" />\Hnewline}}
\Configure{@HEAD}{\HCode{<meta name="generator" content="TeX4ht
(http://www.cse.ohio-state.edu/\string~gurari/TeX4ht/
<http://www.cse.ohio-state.edu/%5Cstring%7Egurari/TeX4ht/>)" />\Hnewline}}
\Configure{@HEAD}{\HCode{<link
rel="stylesheet" type="text/css"
href="\expandafter\csname aa:CssFile\endcsname" />\Hnewline}}
\Configure{@HEAD}{\HCode{<script type="text/javascript"\Hnewline
src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_SVG"\Hnewline
></script>\Hnewline}}
\Configure{@HEAD}{\HCode{<style type="text/css">\Hnewline
.MathJax_MathML {text-indent: 0;}\Hnewline
</style>\Hnewline}}
\begin{document}
\EndPreamble
\def\mathbbm#1{\boldsymbol{\mathbb{#1}}}
\endinput
%-------------------------------------------------------------------
But still I am only able to see normal blackboard font through browser, while the MathML is <mstyle
mathvariant="bold"><mi>ℤ</mi></mstyle>.
Regards
Jagath

Of course here is an example:
\documentclass{scrartcl}
\usepackage{bbm}
\def\Z{\mathbbm{Z}}
\begin{document}
$\Z$
\end{document}
I am not sure what you have in mind. You are right that there is are
Unicode characters for blackboard bold letters. A common solution
in LaTeX would however code it as a blackboard bold font. I have not
checked the implementation of the bbm package, so I do not know what
that one does.
Either way, I am not hellbent on using bbm; any solution which works
in both PDF and XML output is fine.
