To replace the default implementation that the toolkit provides for
the ElementState interface with a new one, add a new data field with the id="state"
in the toolkit configuration file (dse.in) as shown in the following example:
<kColl id="tags">
.....
<kColl id="types">
....
<field id="state" value="myPackageName.myElementStateClassName" />
</kColl>
</kColl>
