Only if the instances differ greatly, and the version control system has no means to track the history of each file. Modern systems like Subversion and Perforce are built around this need.

I think that using the data model (XMI instance) as a reference document is a great suggestion. It eliminates the reliance on a single program, and applies to other groups in the IVOA.

However, it would be nice to see the results of an XSLT to create an XML Schema before accepting the XMI version of the data model as a no normative document
