the XML in the examples was written by me in vi with reference to 
the XML-RPC specification (which means they may contain mistakes -
please shout if you find one).

this is a toolkit issue only in that it looks like your toolkit
is buggy; the XML-RPC spec says

    The body of the response is a single XML structure, a <methodResponse>,
    which can contain a single <params> which contains a single <param>
    which contains a single <value>.

The examples in sec 4.4 are not in any sense meant to be normative, 
they are just illustrations of combining the rules in the rest of the
document with the XML-RPC specification.

Once we get multiple hub implementations using different languages
and different toolkits this sort of thing will show up pretty quickly.
