Well, neither OMF or AAF with embedded audio exported with AD plugin opened in STP when I had tested it from FCPX 10.0.2...
But you can get a sample X2Pro AAF for testing on their forum :

Auditions must be finalized first before exporting the XML to X2Pro.
A few others things good to know :
- For now, X2Pro exports audio with infinite handles. That means that all your audio source is exported. So AAF files can be pretty big. But they plan to add an option to consolidate audio files.
- Audio Roles in Final Cut Pro X are converted into Pro Tools tracks. The tracks in Pro Tools are named upon the role you assigned (track dialogue, track sfx, track french...)
- Multicam is perfectly supported.
- Compound clips are supported, but I haven't tested it.
