Common Cartridge

Files passed the IMS Common Cartridge Validator.
Moodle was able to import CC 1.1 (because there's no code to import 1.2 or 1.3 ?!)
Canvas was able to import CC 1.1, 1.2, and 1.3.
Sakai imports but didn't know what to do with the LTI links? Only empty Frontmatter, Main Body, Backmatter appeared under Lessons. The rest of the content appeared as unusable XML files under Resources. Fixed in 12.4. See this bug report for resolution.
Blackboard was able to import CC 1.1 and 1.2.

Thanks to Ed Beck, Bracken Mosbacker, Brad Payne, Steel Wagstaff and everyone in https://pressbooks.community/ who helped us get this working., _(*42)
