Thank you, but it takes too time learning those new instructions. Also, i

Luckly I have found a simpler solution, having recourse to frame decorations

\xymatrix{ &  & Y\\
&  & 2\,- &  &  & \\
&  & 1\,- & \\
\ar@{-}[rr] & \overset{|}{\overset{}{-1}\,\,\,\,} & O\ar@{>}[uuu]\ar@{>
[rrrr] & \overset{|}{\overset{}{1}} & \overset{|}{\overset{}{2}} &
\overset{|}{\overset{}{3}} & X\\
&  & -1\,-\,\,\,\,\,\\
&  & \ar@{-}[uu]}
