# Base class for classes operating on transactions. Policy and delegation
# classes subclass this class.

# ticket and tx are passed by Data::Conveyor::Transaction::Factory
# constructor call; the factory also passes itself as the factory
# attribute so the transaction can ask the factory to construct
# further objects.
