Validation by JSON Schema

Reports inconsistencies between a YAML file and a JSON Schema if the schema is specified.

Scheme example:

  {
    "properties": {
      "SomeNumberProperty": {
        "type": "number"
      }
    }
  }

The following is an example with the corresponding warning:

SomeNumberProperty: hello world
