I believe the location information is stored in a property named
"_location" that is of type ptolemy.kernel.util.Location
For example, the moml looks like
<property name="_location" class="ptolemy.kernel.util.Location"
value="530.0, 515.0">
</property>
See
ptII/ptolemy/domains/wireless/demo/EvaderAndPursuer/Pursuer.java
for an atomic actor that gets the _location parameter and sends the
x and y location to outputs.
