While experimenting with xml-rpc.el I noticed that (at least to me) the description of `xml-rpc-method-call-async' in xml-rpc.el is misleading. It states:

| Call an XML-RPC method asynchronously at SERVER-URL named METHOD with
| PARAMS as parameters. When the method returns, ASYNC-CALLBACK-FUNC
| will be called with the result as parameter.

The misleading term is 'with the result as parameter'. What I expected to get as parameter for my ASNC-CALLBACK-FUNC is a result list like I do get when doing a sync xmlrpc call. But I noticed that the callback function gets http responses (if any) and operates on a buffer that has to be parsed with `xml-rpc-request-process-buffer' and `xml-rpc-xml-to-response'.

What strenghtend the wrong assumption about `xml-rpc-method-call-async' was the example for a callback function given in the commentary section:

| (defun cb-foo (foo)
| (print (format "%s" foo)))

As FOO won't be a string at all but nil or a list of http responsens.
