Convention is how it was. Partly this is legacy because earlier versions 
of json-schema required the 'allOf' form or everything in addition to 
the $ref would be ignored. I left these thinking more than 1 $ref here 
might be common. But probably more common is a $ref and if/then schemas 
and I'd somewhat rather keep $ref at the top and if/then schemas at the 
bottom. So maybe this is the right direction.

I don't really care to define one way or the other if we can't enforce 
it in the meta-schema. I don't need more nits to look for in reviews. 
Adding a check (i.e. allOf must have 2 or more entries) would be quite 
invasive and wouldn't allow having 1 entry when we expect a 2nd entry 
soonish.
