By default Xfce does not set the required environment variable to make
gtk use the accessibility backend (atk -> gail), i've created a bug
[1] for that, because that is indeed quite important.

To enable this in the toolkit you can do 2 things:
1) Create a .gtkrc-2.0 file in your home-directory and add the line:
gtk-modules="gail:atk-bridge"
2) Export a environment variable GTK_MODULES=gail:atk-bridge

The first one if most likely the best option for you. Once you added
this and restarted X, all applications will send their information to
Orca (tooltips, label, terminal lines, etc). It also looks like that
when 1 or more applications are connected, Orca keeps running.

If you have more questions, problems or Xfce application that are
unaccessible, feel free to report them (if possible new bugs in our
bugzilla, see link below, or this mailing list).
