I'm  new to node.js and I am using this package all the time now. \r\n\r\nSo, if you do:\r\n```\r\n> js = require('jsonschema')\r\n> new js.SchemaError() instanceof  Error\r\ntrue\r\n> new js.ValidationError() instanceof Error\r\nfalse\r\n```\r\nJust wondering if this is by design or in the plans for changing or if I am missing something somewhere (Sorry if this is the case)."}}
