Description:
The transaction component provides the following capabilities.

 * Multi-threading - Supports a protocol for clients to read and write EMF
   models on multiple threads.
 * Model Integrity - Semantic integrity is ensured by automatic validation to
   detect invalid changes and semantic procedures to proactively maintain
   correctness of semantic dependencies.
 * Batched Events - Clients are notified of groups of related changes in
   batches, rather than as a stream of EMF notifications. In particular, this
   allows applications to analyze change sets in their entirety.
 * Undo/Redo - For a simplified programming model, the API automatically tracks
   changes applied to models without the need for client code to use EMF edit
   Commands. These changes are encapsulated in transactions/operations that can
   undo and redo themselves.
 * Editing Domain - Support cooperative editing of models by multiple editors/
   applications. EMF resources can be shared amongst different editing domains.
 * Eclipse Workspace - The API provides traceability between EMF resources and
   workspace resources. Multi-threaded access is coordinated via the Eclipse
   jobs API and its integration with the workspace.
 * Eclipse Operations - The API supports the Eclipse operation history as an
   undo stack for undo/redo of resource changes. The API provides a framework
   for undoable operations that automatically capture undo/redo information,
   which can be interleaved on the same history with dependent operations that
   do not modify the EMF model.
