Projects that attempt to encode variorum texts with the Text Encoding Initiative's Guidelines for Electronic Text Encoding and Interchange will likely encounter situations where the text varies in its structure, as well as in its content. Although encoding textual variants at a separate level using a version control system may be attractive, the advantages in encoding text and variants in the same format are considerable. This paper proposes solutions to three problems that require more than the standard TEI textual critical elements: transposition, variation of meta-data, and insertion of incomplete structures.
