Generally you put common schemas under '$defs' and the then reference
them with '$ref'.

$defs:
  some-prop-type:
    type: integer
    minimum: 0

properties:
  foo:
    $ref: '#/$defs/some-prop-type'
  bar:
    $ref: '#/$defs/some-prop-type'  

Thanks! Is it possible to move the common definitions to a separate
file? I tried to create a file called defs.yaml and change the ref to:

  $ref: "defs.yaml#/$defs/len-or-define"

Oh, oh. Instead of trying to create 3 different "levels" of spec,
and having to pull out shared definitions maybe I can use the 
  if + unevaluatedProperties
to only allow certain properties depending on the value in the
"protocol" attribute...
