      },

      "manufactured":{

        "type":"string",

        "format":"date-time"

      }

    },

## Support for non-standard types and formats

### Ignore unknown JSON formats

```java

final Config cfg = new Config.Builder()

    .ignoreUnknownFormats(true)

    ...

    .build();

```      

### Register custom JSON formats

```java

final Config cfg = new Config.Builder()

    .customTypeMapping(JsonSimpleType.INTEGER, "int64", XsdSimpleType.LONG)

    .customTypeMapping(JsonSimpleType.INTEGER, "int32", XsdSimpleType.INT)

    .customTypeMapping(JsonSimpleType.STRING, "ext-ref", XsdSimpleType.STRING)

    ...

    .build();

```

### Register non-JSON types

```java

final Config cfg = new Config.Builder()

    .nonJsonTypeMapping("date-time", XsdSimpleType.DATE_TIME)

    .nonJsonTypeMapping("int", XsdSimpleType.INT)

    ...

    .build();

```
