13. The method of claim 11 further comprising: determining if there are missing versions of the document that are not included in the set of versions being checked for their geneology. 15. The method of claim 13 further comprising: creating and storing at least one RSID set of values corresponding to at least one of the missing document versions; and applying a logic rule to the created RSID set to determine its position in the version geneology, said logic rule being a test whether for one of any document version in the set, whether the created RSID set corresponding to the missing document version is a subset of the RSID set of the one document, or that the RSID set of the one document is a subset of the created RSID set corresponding to the missing document version.
