Examples
The setProperty command can generally be used as an alternative to addMapEntry if the goal is to give new values to existing keys in a Map. Have the target attribute specify a key of the Map to set that entry's value.
<setProperty target="${contactMap.address}" value="${newAddress}"/>In addition to Maps and their kin, some other value types also have "properties" - such as Files. One could use setProperty to change the title of a File value:
<setProperty target="${composedDoc.title}" value="The Composed Document"/>
