+ <abstract> <p>
+   Subtyping relations for the pi-calculus are usually  defined in a
+syntactic way, by means of  structural rules.  We propose a semantic
+characterisation of channel  types and use it to  derive a subtyping
+relation.   The  type  system  we consider  includes  read-only  and
+write-only channel types, product types, recursive types, as well as
+unions, intersections, and negations  of types which are interpreted
+as  the  corresponding   set-theoretic  operations.   We  prove  the
+decidability  of  the  subtyping  relation,  formally  describe  the
+subtyping  algorithm,  and use  the  techniques  developped for  the
+decidability of  subtyping to prove  the decidability of  the typing
+relation.
+</p><p>
+In order to fully exploit  the expressiveness of the new type system
+(which  subsumes several  existing ones),  we endow  the pi-calculus
+with structured channels where communication is subjected to pattern
+matching that performs dynamic  typecase.  This paves the way toward
+a novel integration of  functional and concurrent features, obtained
+by combining  the pi-calculus  with CDuce, a  functional programming
+language for XML manipulation that is based on semantic subtyping.
