Hi Jeff - thanks so much for responding, and for creating the guide, which I have found very very useful (as well as the developer webinar series and your blog) 
Unfortunately though, I'm still not having any luck with custom subtypes. I've managed to get 4 custom datalists working, but as soon as I try to add subtypes of cm:content (and subtypes of kesn:doc, a subtype of cm:content), I get errors in the log file saying that the bootstrap model could not be imported. Is there something I'm still missing in one of these files?
This is the content of my model file:
