<!--
This file demonstrates how the dojox.wire code can be used to do declarative
wiring of events. Specifically, it shows how you can publish and subscribe
to topics. In this case the setting of a value on one textbox triggers a
publish of that value to a topic. Another invoke is wired to fire when
values are published to that topic which is then displayed in another
textbox.
