addition of document type definitions for project wizard data structures
A document type definition can help to work with corresponding files because it describes the involved data structures to some degree. Such a DTD can be added so that further improvements will become easier for the safe data exchange also around project wizard settings.
A DTD format was standardised as a basis for XML documents. Some technical challenges and limitations were noticed so that another standard like W3C XML Schema evolved. Such a XML schema definition can also be added so that corresponding file handling might become more consistent.
How are the chances to integrate such specifications into your source code repository?
