 * NAME
 *   XMLRPC_ServerRegisterIntrospectionCallback
 * SYNOPSIS
 *   int XMLRPC_ServerRegisterIntrospectionCallback(XMLRPC_SERVER server, XMLRPC_IntrospectionCallback cb)
 * FUNCTION
 *   registers a callback for lazy generation of introspection data
 * INPUTS
 *   server - target server
 *   cb - callback that will generate introspection data
 * RESULT
 *   int - 1 if success, else 0
 * NOTES
 *   parsing xml and generating introspection data is fairly expensive, thus a
 *   server may wish to wait until this data is actually requested before generating
 *   it. Any number of callbacks may be registered at any time.  A given callback
 *   will only ever be called once, the first time an introspection request is
 *   processed after the time of callback registration.
 * SEE ALSO
 *   XMLRPC_ServerAddIntrospectionData ()
 *   XMLRPC_IntrospectionCreateDescription ()
