Data Types

  The {{{http://www.xmlrpc.com/spec}XML-RPC specification}} defines the following
  available data types:

*--------------------+--------------------+-------------------------------------+
| Java Type          | XML Tag Name       | Description                         |
*--------------------+--------------------+-------------------------------------+
| Integer            | <i4>, or           | A 32-bit, signed, and non-null,     |
|                    | <int>              | integer value.                      |
*--------------------+--------------------+-------------------------------------+
| Boolean            | <boolean>          | A non-null, boolean value (0, or    |
|                    |                    | 1).                                 |
*--------------------+--------------------+-------------------------------------+
| String             | <string>           | A string, non-null.                 |
*--------------------+--------------------+-------------------------------------+
| Double             | <double>           | A signed, non-null, double          |
|                    |                    | precision, floating point number.   |
|                    |                    | (64 bit)                            |
*--------------------+--------------------+-------------------------------------+
| java.util.Date     | <dateTime.iso8601> | A pseudo ISO8601 timestamp, like    |
|                    |                    | 19980717T14:08:55. However,         |
|                    |                    | compared to a true ISO8601 value,   |
|                    |                    | milliseconds, and time zone         |
|                    |                    | informations are missing.           |
*--------------------+--------------------+-------------------------------------+
| byte[]             | <base64>           | A base64 encoded byte array.        |
*--------------------+--------------------+-------------------------------------+
| java.util.Map      | <struct>           | A key value pair. The keys are      |
|                    |                    | strings. The values may be any      |
|                    |                    | valid data type, including another  |
|                    |                    | map.                                |
*--------------------+--------------------+-------------------------------------+
| Object[]           | <array>            | An array of objects. The array      |
| java.util.List     |                    | elements may be any valid data      |
|                    |                    | type, including another array.      |
*--------------------+--------------------+-------------------------------------+

  If the property <<<enabledForExtensions>>> is set, then additional data
  types become valid. (Both client and server do support this property.)

*----------------------+--------------------+-------------------------------------+
| Java Type            | XML Tag Name       | Description                         |

*----------------------+--------------------+-------------------------------------+
| Byte                 | <ex:i1>            | A 8-bit, signed, and non-null,      |
|                      |                    | integer value.                      |
*----------------------+--------------------+-------------------------------------+
| Float                | <ex:float>         | A signed, non-null, double          |
|                      |                    | precision, floating point number.   |
|                      |                    | (32 bit)                            |
*----------------------+--------------------+-------------------------------------+
| org.w3c.dom.Node     | <ex:dom>           | A DOM node, which is being          |
|                      |                    | transmitted as an embedded XML      |
|                      |                    | fragment.                           |
*----------------------+--------------------+-------------------------------------+
| Short                | <ex:i2>            | A 16-bit, signed, and non-null,     |
|                      |                    | integer value.                      |
*----------------------+--------------------+-------------------------------------+
| java.io.Serializable | <ex:serializable>  | An object, which is converted into  |
|                      |                    | a serialized representation and     |
|                      |                    | transmitted as a base 64 encoded    |
|                      |                    | byte array.                         |
*----------------------+--------------------+-------------------------------------+
| BigDecimal           | <ex:bigdecimal>    | A BigDecimal                        |
*----------------------+--------------------+-------------------------------------+
| BigInteger           | <ex:biginteger>    | A BigInteger                        |
*----------------------+--------------------+-------------------------------------+
| java.util.Calendar   | <ex:dateTime>      | Unlike the dateTime.iso8601 type,   |
|                      |                    | this is a full blown xs:dateTime    |
|                      |                    | value. In particular, it includes   |
|                      |                    | milliseconds, and timezone settings.|
