Array validation does not comply with JSON Schema spec when items schema is specified

[bugventure]

When validating arrays and an items schema is specified in the form of array of schemas, validation fails if the validated array contains less items than specified by items. This is not compliant with JSON Schema: items and additionalItems spec . In section 5.3.1.3. Example, the spec clearly indicates that arrays with fewer items than specified by the items array in the schema are valid.

Example:

var schema = {
    type: 'array',
    items: [
        { type: 'string' },
        { type: 'integer' }
    ]
};

validator(schema).validate([]);    // throws, in conflict with the JSON Schema spec
