dotted or colored arc in \xymatrix

Question

Does not arrows style or color option apply an arc in \xymatrix? Please let me know the way.

\documentclass{article}
\usepackage[arrow, matrix]{xy}
\begin{document}
  \[
    \xymatrix{
      A \ar@{.>} `d[r] `r[dr] [dr]& \\ & B
    }
  \]
\end{document}

Hello Yuki, welcome to the site. If you indent your lines with 4 spaces they are marked as code. So you don't need to escape the markup chars. — percusse, Dec 25 '13 at 11:49
Does Coloring arrows in \xymatrixhelp or Commutative diagram with curved arrows, colour, and changing the style of arrows you? — moewe, Dec 25 '13 at 12:07
I could color or dot the straight parts of the arrow like your links, but the arc parts are not changed. — Yuki, Dec 25 '13 at 12:19
It might be a lot more flexible if you use the tikz-cd package instead. It is almost the same syntax, the arrow macros are named differently. Plus the bonus of all the tikz tricks — daleif, Dec 25 '13 at 13:07
Thanks daleif, I had achieved my purpose to use tikz-cd. How merciless the changes of mainstreams! — Yuki, Dec 26 '13 at 06:41
@Yuki Have found some solution to your problem in the meantime? I would be very interested. If not, you could accept my answer in order to close this post as solved or you rewrite your question asking explicitly for xy and I will put a bounty on it. Thanks. — LaRiFaRi, May 22 '15 at 08:58

I do not manage to obtain your desired result with xy. But here you have a solution with tikz-cd:

% arara: pdflatex 

\documentclass{article}
\usepackage{tikz-cd}

\begin{document}
    \[
    \begin{tikzcd}
    A \arrow[draw=none]{dr}[name=aux, anchor = center]{} \arrow[rounded corners=7pt, dotted, red, to path={ (\tikztostart.south)
                      |- (aux.center) \tikztonodes
                      -| (\tikztotarget.north)
                      }]{dr}& \\
    & B
    \end{tikzcd}
  \]
\end{document}
