Possible issue with @type from JSON document in schema ?? Not quite sure. I'm not sure why this JSON doesn't validate

var fs = require('fs');
var jjv = require('jjv');

var X3dJsonSchema = {
"$schema": "http://json-schema.org/draft-04/schema#",
"title": "JSON Schema X3D V3.3",
"description": "Development JSON Schema for X3D V3.3 ",
"type": "object",
"properties": {
"NavigationInfo": {
"type": "object",
"properties": {
"@type": {
"type": "array",
"minItems": 1,
"items": [
{
"type": "string",
"default": "EXAMINE"
},
{
"type": "string",
"default": "ANY"
}
],
"additionalItems": {
"type": "string"
}
}
},
"additionalProperties": false
}
}
};

var env = jjv();
env.addSchema('x3djson', X3dJsonSchema);

function validateJSON() {
try {
var hello = {
"NavigationInfo": {
"@type": ["EXAMINE"]
}
};

    var errors = env.validate('x3djson', hello);

    if (!errors) {
        console.log('jjv Valid');
    } else {
        console.log('jjv Validation failed.');
        console.log('jjv Validation errors:');
        console.log(JSON.stringify(errors));
    }
} catch (e) {
    console.log('Failed JSON parse');
}

}

validateJSON();

It could be how arrays are validated as well.

2 other JSON validators pass this. I would like to know if they are wrong or not.
