title: JSON Schema type integer
body: <p>In the spec <a href="http://json-schema.org/latest/json-schema-core.html" rel="nofollow noreferrer">http://json-schema.org/latest/json-schema-core.html</a>, it only list below types:
  null,
  boolean,
  string,
  number,
  object,
  array.</p>
  
  <p>I know number includes integer, but can I define a "type":"integer" explicitly. I mean will this violate the spec?</p>
