Xoom 3.8.2

This is a minor patch release. It fixes a bug in the Service Optimization Scheme implementation that previously required a newly created Collection's ProductName to be globally unique. On the Service Optimization side, this requirement is only true for top-level Collections, while for child Collections (such as multi-values) ProductName only needs to be unique within the scope of their parent Collection. The fix takes this into account and corrects the behaviour.
