IncrementFormat is the interface implemented by Objects that convert local
subscription data for transportation to other agents (aggregation agents,
generally). Information obtained through the SubscriptionAccess interface
can be translated in an arbitrary manner into an UpdateDelta, which is
then shipped off as an XML document.
For many purposes, it suffices to use XmlIncrement (q.v.) with a suitable
implementation of XMLEncoder, which is easier than creating a custom-built
IncrementFormat from scratch.
