   @zeroshade do you have thoughts here?  Being able to pass in an external schema is useful in some contexts.
   
   Would it be workable to have the following logic:
   ```
   if (passedInSchema) {
     message = readMessage()
     if (message.isSchema) {
       validate(message.schema, passedInSchema)
       message = readMessage()
     }
   }
   ```
   
   Make sense?
