I have updated the ODF Conformance/Compliance Assurance Helix sketch at <https://cwiki.apache.org/confluence/display/Corinthia/ODF>.
The connected treatment of ODF 1.2 Conformance that has been linked from that sketch has also been updated. That overview is at <http://nfoworks.org/notes/2014/06/n140602.htm> and a trial diagram of the different conformance layers is at <http://nfoworks.org/notes/2014/06/n140602b.htm>. I am starting to put more effort into this material, including coming up with minimal test cases as baby steps. - Dennis
