Validation for optional objects about z-schema

[zaggino]

By the specification, you should use anyOf for the 1) but to make it easier for you can use custom format defined like this:

ZSchema.registerFormat("hasAtLeastOneProperty", function (obj) {
    return Object.keys(obj).length > 0;
});

For 2) you should use dependencies, take a look at http://json-schema.org/latest/json-schema-validation.html#anchor70

Here's a test suite that might give you more ideas on how to use it:

{
        "description": "dependencies",
        "schema": {
            "dependencies": {"bar": ["foo"]}
        },
        "tests": [
            {
                "description": "neither",
                "data": {},
                "valid": true
            },
            {
                "description": "nondependant",
                "data": {"foo": 1},
                "valid": true
            },
            {
                "description": "with dependency",
                "data": {"foo": 1, "bar": 2},
                "valid": true
            },
            {
                "description": "missing dependency",
                "data": {"bar": 2},
                "valid": false
            },
            {
                "description": "ignores non-objects",
                "data": "foo",
                "valid": true
            }
        ]
    }
