+ * Applications make changes to the local data tree in the transaction by via the
+ * <b>put</b>, <b>merge</b>, and <b>delete</b> operations.
+ *
+ * <h2>Put operation</h2>
+ * Stores a piece of data at a specified path. This acts as an add / replace
+ * operation, which is to say that whole subtree will be replaced by the
+ * specified data.
+ * <p>
+ * Performing the following put operations:
+ *
+ * <pre>
+ * 1) container { list [ a ] }
+ * 2) container { list [ b ] }
+ * </pre>
+ *
+ * will result in the following data being present:
+ *
+ * <pre>
+ * container { list [ b ] }
+ * </pre>
+ * <h2>Merge operation</h2>
+ * Merges a piece of data with the existing data at a specified path. Any pre-existing data
+ * which is not explicitly overwritten will be preserved. This means that if you store a container,
+ * its child lists will be merged.
+ * <p>
+ * Performing the following merge operations:
+ *
+ * <pre>
+ * 1) container { list [ a ] }
+ * 2) container { list [ b ] }
+ * </pre>
+ *
+ * will result in the following data being present:
+ *
+ * <pre>
+ * container { list [ a, b ] }
+ * </pre>
+ *
+ * This also means that storing the container will preserve any
+ * augmentations which have been attached to it.
+ *
+ * <h2>Delete operation</h2>
+ * Removes a piece of data from a specified path.
+ * <p>
+ * After applying changes to the local data tree, applications publish the changes proposed in the
+ * transaction by calling {@link #submit} on the transaction. This seals the transaction
