title: How do I validate a JSON Schema schema, in Python?
body: <p>I am programmatically generating a JSON-Schema schema.  I wish to ensure that the schema is valid.  Is there a schema I can validate my schema against?</p>
  
  <p>Please note my use of schema twice in that sentence and the title.  I don't want to validate data against my schema, I want to validate my schema.</p>
