Hi Travis,
There's some terminology confusion. Data are values meant to be
directly put into the context, they are not tool properties. Tool
properties are configured like this:
<tools>
<toolbox scope="request" thisIsAPropertyForAllToolsInThisToolbox="hello">
<property name="aTypedPropertyForAllToolsInThisToolbox"
value="true" type="boolean"/>
<tool key="my" class="org.mine.MyTool"
thisIsAPropertyForThisToolOnly="world"/>
</toolbox>
<property name="aPropertyForAllToolsInAnyToolbox" value="10" type="number"/>
</tools>
See: http://velocity.apache.org/tools/devel/config.xml.html
