Pandoc-generated PDF: Change list numbering style - latex

Question

What is the way to change the style of numbers in ordered lists generated by Pandoc?
For the following Markdown input
1. One
2. Two
1. Sub 1
2. Sub 2
Pandoc generates the following Latex output
\begin{enumerate}
\def\labelenumi{\arabic{enumi}.}
\itemsep1pt\parskip0pt\parsep0pt
\item
One
\item
Two
\begin{enumerate}
\def\labelenumii{\arabic{enumii}.}
\itemsep1pt\parskip0pt\parsep0pt
\item
Sub 1
\item
Sub 2
\end{enumerate}
\end{enumerate}
This results in the following PDF output:
1. One
2. Two
1. Sub 1
2. Sub 2
While I'm trying to achieve
1. One
2. Two
2.1. Sub 1
2.2. Sub 2
I tried to redefine style of numbering in the default template with these commands
\renewcommand{\labelenumii}{\theenumii}
\renewcommand{\theenumii}{\theenumi.\arabic{enumii}.}
but as Pandoc generates explicit definition for labelenumii this solution does not work.
Update
It turns out that the problem could be resolved by using #. notation instead of 1. one. For whatever reason Pandoc skips styling only for lists defined this way and interprets the standard Markdown notation as an instruction to style list with plain numbers. Hopefully in future versions it will be a bit more flexible and will add the support for nested numbers in lists.

edit
This function of the latex writer that adds the \def\labelenumi{} part checks for numstyle == DefaultStyle && numdelim == DefaultDelim. As #oleg found out, this might be accomplished with #. list markers, so that this should work:
---
header-includes:
- \renewcommand{\labelenumii}{\theenumii}
- \renewcommand{\theenumii}{\theenumi.\arabic{enumii}.}
---
#. One
#. Two
#. Sub 1
#. Sub 2
There are two feature requests asking for a native markdown solution on the issue tracker (336 and 1627), as well as a discussion on the mailing list.
pre-edit answer
Of course, you could always compile to latex, postprocess the file to remove those \def\labelenumi{} lines, and then compile the latex file. Here is an example that works with the standard latex template.
test.md
---
header-includes:
- \renewcommand{\labelenumii}{\theenumii}
- \renewcommand{\theenumii}{\theenumi.\arabic{enumii}.}
---
1. One
2. Two
1. Sub 1
2. Sub 2
commands:
pandoc test.md -t latex -s | sed '/\\def\\labelenumi/d' > test.tex
xelatex test.tex
But all the lists of your document will be affected, and you need to write the latex compilation commands yourself.
