No reason why that has to be, e.g.:

    <annotation name="comment">
        This signal is sent every time the clock chimes.
        The argument is the number of clock strikes.

That’s OK, I was planning to generate it automatically from Python
docstrings on the server end, and conversely incorporate it
automatically into docstrings for the proxy interface at the client end.
I just want the payload in the introspection format to be plain text.
