A filter always contains the "main" table and, possibly, other tables. The filter always starts message processing with the "main" table. A table is defined in a filter with the <table> tag. Each table must have a unique name defined in the name attribute of the <table> XML tag. A table may have an optional comment in the <comment> XML tag.

For example:

<?xml version="1.0" encoding="utf-8"?>
<filter name="main filter" version="1.0">
 <comment>This is a comment.</comment>
   <table name="main">
     <comment>This is a comment for the table "main".</comment>
       ...
   </table>
 
   <table name="spam">
       ...
   </table>
 
</filter>

This filter has two tables: the mandatory main table and an optional spam table.
