Lavoisier

Should be available from both "lavoisier-standalone-execute" and web service.
Should be available without restarting the engine.

Solution:

<view name="stoppoint">
    <argument name="view"/>
    <argument name="processor">999</argument>
    <connector type="XMLConnector">
        <parameter name="content" eval="view($view, arguments() | entry('_processor_', $processor))"/>
    </connector>
</view>
<view name="example">
    <connector type="..."/>
    <processors>
        <processor disabled="arguments()/*/*[@key='_processor_'] &lt; 1"/>
        <processor disabled="arguments()/*/*[@key='_processor_'] &lt; 2"/>
    </processors>
</view>
