It's not so hard.
Dig a hole:
\xymatrix{ \ar[dr]|\hole & \\ \ar[ur] & }
Calculate the intersection point and dig a hole:
\xymatrix{ \ar[drr]|!{[d];[r]}\hole & & \\ \ar[ur] & & }
Here is my solution — I can't do anything better without a MWE.
\documentclass{article}
\usepackage[all]{xy}
\newdir{d}{{\subset}}
\begin{document}
\[
\xymatrix{
A \ar@{}[r]|{\subset} & B\\
A \ar@{-*{\subset}}[r] & B\\
A \ar@{-d}[r] & B\\
A \ar@{-d}[r]-<10pt,0pt> & B
}
\]
\end{document}
The \newdir command allows to define shorthand.
And the result :
Note that you can find some help in the xyguide pages 5 and 6.
