Issue

I'm trying to define a JSON schema with a type like:

{ type: 'object',
  properties: {
    point: {
      type: 'object',
      properties: {
        x: { type: 'integer' },
        y: { type: 'integer' }
      }
    }
  }
}

It fails, though, because x and y don't match the regex ^[a-zA-Z][[a-zA-Z0-9_]*]?[a-zA-Z0-9]$.

Can it be changed to something like ^[a-zA-Z](?:[[a-zA-Z0-9_]*]?[a-zA-Z0-9])?$ so only the first letter is mandatory?
