| Subject: | Small error in POD |
In JSON-Schema-0.016 POD there is an example:
```
my $validator = JSON::Schema->new({
properties => {
'time' => { type => ['DateTime','string'] },
},
});
my $object = {
'time' => DateTime->now;
};
my $result = $schema->validate($object);
```
But this example is incorrect. The last line in the example should be changed to:
```
my $result = $validator->validate($object);
```
