Shorter submissions (10 or less pages) are encouraged. All submitted papers will be judged on their quality, originality, and relevance to the symposium.

All authors of accepted papers will be expected to sign copyright release forms, as necessary. One author of each accepted paper will be expected to present it at the conference.

All papers must be submitted electronically at http://www.easychair.org/XSYM2007/

Proceedings of the symposium will be published by Springer-Verlag in Lecture Notes in Computer Science (http://www.springer.de/comp/lncs).
