Choosing best XMI version

[gakopp]

I'm working with an open-source product (ArchGenXML for Plone Archetypes) that generates specialized code from UML model XMI files.  ArchGenXML purportedly handles XMI versions 1.0, 1.1 and 1.2.  However, it has problems with EA's XMI in all three of these versions.  I'm going to "fix" ArchGenXML (a Python program) so that it correctly handles EA-exported XMI (an issue of standards interpretation, no doubt).  It makes sense to do this for only one version of XMI.

My question for the community/Sparx is: which version of XMI, 1.0, 1.1, or 1.2, is implemented the best in Enterprise Architect, in terms of standards compliance, stability, and other factors?
