<dt>USE
<dd>Use this elementary stream.
<dt>ONCE
<dd>Use this elementary stream only once per service type.
The language is distinguished, too.
The first successfully compared rule wins.
<dt>ONE_TIME
<dd>Use this elementary stream only one time per service type (like
video, audio, subtitles) and language. The first sucessfully
compared rule wins. For example, when one AC3 elementary stream
is marked to be used with 'eng' language and another rule with
the ONE_TIME action was matched, the new AC3 elementary stream
will not be added if the language for new AC3 elementary stream
is 'eng'. Note that the second rule might not have the language
filter (column) set.
<p>
For the CA filter, this rule means that the new CA elementary stream
is added only if another CA is not already used.

<dt>EXCLUSIVE
<dd>Use only this elementary stream. No other elementary streams
