I have a huge JSON schema with a part of it looking like this:

   "if":{
      "required":[

      ],

               ],
               "properties":{

                  }

I want to call JSchema.Load() on it. The problem is that depth of that JSON exceeds default MaxDepth = 64 and Load() method throws Newtonsoft.Json.JsonReaderExceptio. My code looks like this:

using (var stringReader = new StringReader(json))
using (var jsonReader = new JsonTextReader(stringReader))
{
    var schema = JSchema.Load(jsonReader);
}

I’ve tried to set JsonTextReader.MaxDepth to 256 but then I get StackOverflowException.
I wrote custom JsonTextReader implementation which shouldn’t go deeper after reaching maxDepth:

class DepthLimitingJsonReader : JsonTextReader
    {
        private readonly int _maxDepth;
        private int _currentDepth;

        public DepthLimitingJsonReader(TextReader reader, int maxDepth)
            : base(reader)
        {
            _maxDepth = maxDepth;
            _currentDepth = 0;
        }

        public override bool Read()
        {
            bool result = base.Read();

            if (result)
            {
                if (TokenType == JsonToken.StartObject || TokenType == JsonToken.StartArray)
                {
                    _currentDepth++;
                    // If depth exceeds maxDepth, skip the content inside this object or array
                    if (_currentDepth > _maxDepth && Path.EndsWith("else"))
                    {
                        Skip();
                    }
                }
                else if (TokenType == JsonToken.EndObject || TokenType == JsonToken.EndArray)
                {
                    _currentDepth--;
                }
            }

            return result;
        }
    }

But anyway Skip() method process tokens deeply within the structure and still exceptions are thrown. I want ignore everything what is deeper than maxDepth. How can I do that?
