The Drop Processor is a special processor that only requires a blacklist and whitelist as configuration. When triggered, the RAS message will be dropped. If you fail to specify a whitelist or blacklist, all RAS messages will be dropped.
Example XML:
<DropProcessor>
<WhiteList>
<Item key="category" value="JINGLE" />
</WhiteList>
<BlackList>
<Item key="title" value="Special Jingle" />
</BlackList>
</DropProcessor>
