Contractual Arbitration Clauses and Non-Contractual Claims

Are non-contractual claims such as tort claims covered by standard arbitration clauses? Italian arbitration law contains a provision which seems to resolve this issue in favour of arbitration but which is interpreted restrictively by the Italian Court of Cassation. In other jurisdictions, the traditional approach was to find the answer by interpreting the wording of the clause. The modern view is to focus instead on the requirement of 'factual equivalence' between the non-contractual claim and the performance of the contract that contains the arbitration clause.
