5. A computer-implemented method for reconstituting a document in a repository in a content management system, the method comprising the steps of: during initial reconstitution of the document, performing the steps of: (A) retrieving from the repository objects corresponding to original links in the document; (B) storing values from the retrieved objects in corresponding fallback elements in the document; (C) generating a list with the original links in the document and corresponding voidable links; and (D) replacing any original link in the document that is not voidable with a corresponding voidable link defined in the list, during each subsequent reconstitution of the document that follows the initial reconstitution of the document in steps (A) through (D), performing the steps of: (E) determining the original links in the list for the document; (F) querying the repository to determine which of the objects corresponding to the original links in the list have not changed since the last reconstitution of the document; and (G) for each object that has not changed since the last reconstitution of the document, invalidating a corresponding voidable link.

The method of claim 5 wherein the invalidation of the corresponding voidable link in step (G) causes using the fallback element corresponding to the voidable link as the value for the voidable link when the document is reconstituted.
