There has been public demand for a @docStatus on the <edition> element, (TEI-L 2009-06-25+)primarily to be used in the <editionStmt> to indicate the status of the current edition of the document. This is different from change management, as many changes might be made on a document of the same status 'draft', but it might go from 'pending' to 'approved' with no change of text.
Sample values for an enumerated but open list might include some of the following suggestions:
datatype might be one of data.enumerated
Examples should possibly include a <date> inside the <edition> noting the date the edition reached that status.
