You need a '/' between '#' and 'definitions'.

This particular check is in master, but not yet a release on pypi. I'll 
be tagging a release soon.

I've got this problem that adding new meta-schema checks like this one 
requires fixing up all the existing in tree schemas first. So I give 
some amount of time before adding them to a tagged release. However, I 
want to start testing new schemas right away. I haven't come up with a 
better solution short of importing the meta-schema into the kernel tree 
or separately versioning them.
