Thanks to #1168 we can belatedly catch some bugs in extension definitions. These are in the health-lifesci definitions (/cc @twamarc) and the pending draft for courses (/cc @philbarker #195), and the health-related pending proposal #1062 for ushealthcare descriptions (/cc @vholland).

I will simply comment out all the corresponding domain/range assertions for now, except for Url -> URL.

I note for courses we ought to talk about whether 'credential' and 'certificate' work well as names; to a broader tech audience they could look like crypto terminology rather than educational.
