A description of the hierarchically-structured document is accessed and converted into an early-bound object having at least some of the same properties as the hierarchically-structured document, and having at least some of the methods that may be performed on the hierarchically-structured document. When a function call is placed to the early-bound object, the early-bound object causes the appropriate corresponding changes to be affected on the hierarchically-structured document while maintaining change tracking information for the document. This reduces the difficulty when drafting source code for a program that interfaces with hierarchically-structured documents that can have varying structures and may be governed by complex change tracking rules.
