        <maxThreads>4</maxThreads>
        <capacity>100</capacity>
        <clearCompletedAfterSeconds>300</clearCompletedAfterSeconds>
        <category>somecategory1</category>
        <category>somecategory2</category>
    </queue>

- id is the queue id.

- name is the human-readable name.

- capacity when specified make the queue bounded, the scheduling of new work is blocking when the queue is full (default unlimited).

- clearCompletedAfterSeconds (default 3600) is the delay after which completed work may be automatically cleared from its queue. 0 means never.

- category is a list of Work categories that this queue will receive. For event listeners work, the category is the listener name (or its simple class name).
