Implemented as the cancel command of the control tool described in Pattern 19. This cancel command removes an entire flow instance from work. As currently implemented, it doesn't affect children flows and parent flows.

OpenWFE 1.7.0 brings a new expression : <cancel-process>. Explicit termination of a flow is now possible from the definition. Consider :

    <sequence>

        <participant ref="alpha" />

        <if>
            <equals field-value="exit" other-value="true" />
            <cancel-process/>
        </if>

        <participant ref="bravo" />
        <participant ref="charly" />

    </sequence>

If the participant 'alpha' did set a field named 'exit' to the value 'true', participants 'bravo' and 'charly' will never be reached by the flow.
