20200806 not(.) is most commonly used in primitive constraints. Someone needs to go in and replace the the not(.) with appropriat handcrafted constraints. Someone should walk through the 5 examples, and come up with the schematron expresions ought to be. 20200820 Matt had some proposed schematron code for the group to review found here: https://gist.github.com/mjszczep/c815a16c788eba587f7fff414519cc42 One change to the schematron was discussed that needs to be tested. We will come back to this next week. 20200827 Matt reports that he tested the proposed changes and has not identified any issues. Motion: Implement the schematron constraints as identified in this link: https://gist.github.com/mjszczep/c815a16c788eba587f7fff414519cc42 Matt S/ Benjamin F, Opposed-0, Abstain-0, In favor-19
