wherein the one or more changes include at least one of an addition, a deletion, or an update;
determining the portion affected by the one or more changes; and
sending, to the server to be stored in persistent storage, data that indicates the one or more changes and the portion affected by the one or more changes without sending, to the server to be stored in the persistent storage, data that represents elements that are outside of the portion;

Abstract
Techniques for incrementally saving documents are provided. A document processor reads a document that is represented by a tree of nodes. The document processor, in response to an instruction to make a change to the tree, determines a set of nodes from the tree that are affected by the change. The document processor sends an instruction to transfer and store only the set of nodes without causing nodes outside of the set to be stored.
