+
+* Composite fields
+
+  Another new feature introduced in 1.9 is the CompositeField. This is a CustomField that acts
+  as a container for several IsoValues, and it can be configured in the parsing guide of
+  a message type:
+
++-----
+<parse type="0410">
+    <field num="125" type="LLLVAR">

+        <field num="4" type="ALPHA" length="2" />
+    </field>
+</parse>
++-----
+
+  In the above example, when a message with type 0410 is parsed, the value for field 125 will
+  be a <<<CompositeField>>> and you can obtain the subfields via <<<getField()>>> or
+  <<<getObjectValue()>>>. The <<<num>>> attribute of the subfields is ignored; it's just
+  there to pass the DTD validation.
+
+  This means that you can do this via code:
+
++-----
+//Assuming original data for field 125 is "018one  03two123456OK"
+CompositeField f = message.getObjectValue(125);
+String sub1 = f.getObjectValue(0); //"one  "
+String sub2 = f.getObjectValue(1); //"two"
+String sub3 = f.getObjectValue(2); //"123456"
+String sub4 = f.getObjectValue(3); //"OK"
++-----
+
+  You can also create a CompositeField, store several subfields inside it, and store it in any
+  field inside an IsoMessage, specifying the same instance as the CustomField:
+
++-----
+CompositeField f = new CompositeField().addValue(new IsoValue<String>(IsoType.ALPHA, "one", 5))
+    .addValue(new IsoValue<String>(IsoType.LLVAR, "two"))
+    .addValue(new IsoValue<Long>(IsoType.NUMERIC, 123l, 6))
+    .addValue(new IsoValue<String>(IsoType.ALPHA, "OK", 2));
+message.setValue(125, f, f, IsoType.LLLVAR, 0);
++-----
+
+  When the message is encoded, field 125 will be "<<<018one  03two000123OK>>>".

+* Campos compuestos
+
+  Otra característica nueva a partir de la versión 1.9 son los campos compuestos, por medio de la clase
+  CompositeField, que es una implementación de CustomField que funciona como un contenedor de varios
+  IsoValues, y puede ser configurado en la guía de lectura de un tipo de mensaje:

+        <field num="4" type="ALPHA" length="2" />
+    </field>
+</parse>
++-----
+
+  En este ejemplo, cuando un mensaje tipo 0410 se decodifica, el valor del campo 125 será una instancia
+  de <<<CompositeField>>> y se pueden obtener sus subcampos con los métodos <<<getField()>>> y
+  <<<getObjectValue()>>>. El atributo <<<num>>> de los subcampos es ignorado; simplemente se tiene que
+  incluir para pasar la validación del DTD.
+
+  Lo anterior significa que se puede hacer esto con código, una vez que se ha leído el mensaje:
+
++-----
+//Suponiendo que originalmente el campo 125 trae "018one  03two123456OK"
+CompositeField f = message.getObjectValue(125);
+String sub1 = f.getObjectValue(0); //"one  "
+String sub2 = f.getObjectValue(1); //"two"
+String sub3 = f.getObjectValue(2); //"123456"
+String sub4 = f.getObjectValue(3); //"OK"
++-----
+
+  También se puede crear un CompositeField, guardar varios valores en él, y luego ponerlo
+  como valor en cualquier campo de un IsoMessage, usando el mismo objeto como CustomField:
+
++-----
+CompositeField f = new CompositeField().addValue(new IsoValue<String>(IsoType.ALPHA, "one", 5))
+    .addValue(new IsoValue<String>(IsoType.LLVAR, "two"))
+    .addValue(new IsoValue<Long>(IsoType.NUMERIC, 123l, 6))
+    .addValue(new IsoValue<String>(IsoType.ALPHA, "OK", 2));
+message.setValue(125, f, f, IsoType.LLLVAR, 0);
++-----
+
+  Cuando ese mensaje sea codificado, el campo 125 se verá como "<<<018one 03two000123OK>>>".
