Remarks

Additions, deletions, and significant recoding should be noted, but not correction of minor typographical errors. It is recommended that revisions should be entered in reverse chronological order, with the most recent change first. The resp attribute contains a pointer to an element containing info about the person/entity responsible for change. The edition element can be used to designate an MEI encoding that has been so substantively changed that it constitutes a new version that supersedes earlier versions.This element is modelled on an element in the Encoded Archival Description (EAD) standard.

Constraints
The date of the change must be recorded in an isodate attribute or date element.
The person responsible for the change must be recorded in a resp attribute or respStmt element.
