If set, all keywords and their sub keywords are catenated to a single step in the result when possible. For example:

        <kw name='Open site'>
            <kw name='Open URL'>
                <kw name='Navigate browser'>
                ...
                </kw>
            </kw>
        </kw>
        ...
        

.. the test case result is added with a single step described as 'Open site - Open URL - Navigate browser'. Note that when concatenating and a step fails it is always included as a separate step.

If not set, each sub keyword will generate a separate step to the result.
