示例4: XmlStreamStub

    Instances of this stub hold an object in L{xmlstream} that acts like an

    initialization. Stanzas can be sent through it by calling its C{send}
    method with an object implementing
    L{IElement<twisted.words.xish.domish.IElement>} as its first argument.
    These appear in sequence in the L{output} instance variable of the stub.

    For the reverse direction, stanzas passed to L{send} of the stub, will be
    dispatched in the stubbed XmlStream as if it was received over the wire, so
    that registered observers will be called.
