4 Foreword ETAPS 2008 was the 11th instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprised five conferences (CC, ESOP, FASE, FOSSACS, TACAS), 22 satellite workshops (ACCAT, AVIS, Bytecode, CMCS, COCV, DCC, FESCA, FIT, FORMED, GaLoP, GT-VMT, LDTA, MBT, MOMPES, PDMC, QAPL, RV, SafeCert, SC, SLA++P, WGT, and WRLA), nine tutorials, and seven invited lectures (excluding those that were specific to the satellite events). The five main conferences received 571 submissions, 147 of which were accepted, giving an overall acceptance rate of less than 26%, with each conference below 27%. Congratulations therefore to all the authors who made it to the final programme! I hope that most of the other authors will still have found a way of participating in this exciting event, and that you will all continue submitting to ETAPS and contributing to make of it the best conference in the area. The events that comprise ETAPS address various aspects of the system development process, including specification, design, implementation, analysis and improvement. The languages, methodologies and tools which support these activities are all well within its scope. Different blends of theory and practice are represented, with an inclination towards theory with a practical motivation on the one hand and soundly based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive. ETAPS is a confederation in which each event retains its own identity, with a separate Programme Committee and proceedings. Its format is open-ended, allowing it to grow and evolve as time goes by. Contributed talks and system demonstrations are in synchronized parallel sessions, with invited lectures in plenary sessions. Two of the invited lectures are reserved for unifying talks on topics of interest to the whole range of ETAPS attendees. The aim of cramming all this activity into a single one-week meeting is to create a strong magnet for academic and industrial researchers working on topics within its scope, giving them the opportunity to learn about research in related areas, and thereby to foster new and existing links between work in areas that were formerly addressed in separate meetings. ETAPS 2008 was organized by the John von Neumann Computer Society jointly with the Budapest University of Technology and the Eötvös University, in cooperation with: European Association for Theoretical Computer Science (EATCS) European Association for Programming Languages and Systems (EAPLS) European Association of Software Science and Technology (EASST) and with support from Microsoft Research and Danubius Hotels.

I would like to express my sincere gratitude to all of these people and organizations, the Programme Committee Chairs and members of the ETAPS conferences, the organizers of the satellite events, the speakers themselves, the many reviewers, and Springer for agreeing to publish the ETAPS proceedings. Finally, I would like to thank the Organizing Chair of ETAPS 2008, Dániel Varró, for arranging for us to have ETAPS in the most beautiful city of Budapest January 2008 Vladimiro Sassone

6 Preface The present volume contains the proceedings of the 11th international conference on the Foundations of Software Science and Computations Structures (FOS- SACS) 2008, held in Budapest, Hungary, April 2 4, FOSSACS is an event of the Joint European Conferences on Theory and Practice of Software (ETAPS). The previous ten FOSSACS conferences took place in Lisbon (1998), Amsterdam (1999), Berlin (2000), Genoa (2001), Grenoble (2002), Warsaw (2003), Barcelona (2004), Edinburgh (2005), Vienna (2006), and Braga (2007). FOSSACS presents original papers on foundational research with a clear significance to software science. The Programme Committee invited papers on theories and methods to support analysis, synthesis, transformation and verification of programs and software systems. In particular, we identified the following topics: algebraic models, automata and language theory, behavioral equivalences, categorical models, computation processes over discrete and continuous data, infinite state systems, computation structures, logics of programs, modal, spatial, and temporal logics, models of concurrent, reactive, distributed, and mobile systems, process algebras and calculi, semantics of programming languages, software specification and refinement, type systems and type theory, fundamentals of security, semi-structured data, program correctness and verification. We ultimately received 124 submissions. This proceedings volume consists of the abstract of an invited talk by Igor Walukiewicz together with 33 contributed papers. The contributed papers were selected for publication by the Programme Committee during a two-week electronic discussion. We sincerely thank all the authors of papers submitted to FOSSACS 2008; we were pleased indeed by the number and quality of the submissions. Moreover, we would like to thank the members of the Programme Committee for their excellent job during the selection process. Clearly, all this would not have been possible without the valuable and detailed reports provided by the sub-reviewers. Also, through the phases of submission, evaluation, and production of the proceedings we relied on the invaluable assistance of the EasyChair system. Last but not least, we would also like to thank the ETAPS 2008 Organizing Committee chaired by Dániel Varró and the ETAPS Steering Committee chaired by Vladimiro Sassone for their efficient coordination of all the activities leading up to FOSSACS January 2008 Roberto M. Amadio
