Starting with <emphasis>4.0</emphasis>, when specifying
a <code>value</code> attribute, you can also specify an optional
<code>type</code> attribute. When the destination is a
typed setter method, the framework will coerce the value
appropriately (as long as a <classname>PropertyEditor</classname>)
exists to handle the conversion. If however, the target
payload is a <interfacename>Map</interfacename> the
entry will be populated with the value without conversion. The
<code>type</code> attribute allows you to, say, convert
a String containing a number to an <classname>Integer</classname>
value in the target payload.
