-/**
- *  An XML-RPC client implemented as a JavaScript Host Object. See the
- *  Ibex spec for information on its behavior.
- *
- *  NOTE: this client is EXTREMELY lenient in the responses it will
- *  accept; there are many, many invalid responses that it will
- *  successfully parse and return. Do NOT use this to determine the
- *  validity of your server.
- *
- *  This client conforms to <a href="http://www.xmlrpc.com/spec">The
- *  XML-RPC Spec</a>, subject to these limitations:
- *  <ol>
- *    <li> XMLRPC cannot invoke methods that require a <base64/> argument
- *    <li> if a return value contains a <base64/>, it will be returned as a string
- *    <li> The decision to pass a number as <i4/> or <double/> is based
- *         entirely on whether or not the argument is fractional. Thus, it
- *         is impossible to pass a non-fractional number to an xmlrpc
- *         method that insists on being called with a <double/> element. We
- *         hope that most xml-rpc servers will be able to automatically
- *         convert.
- *  </ol>

-     *  stack to the last null, replace it with a NativeJSArray, and
-     *  insert into it all elements above it on the stack.
-     *
-     *  If a &lt;struct&gt; tag is encountered, a JSect is pushed
-     *  onto the stack. If a &lt;name&gt; tag is encountered, its CDATA is
-     *  pushed onto the stack. When a &lt;/member&gt; is encountered, the
-     *  name (second element on stack) and value (top of stack) are
-     *  popped off the stack and inserted into the struct (third
-     *  element on stack).
