I'm trying to get my head around the complexity of the huge XML::Compile namespace.

Like I wanted to change the connection timeout from the default to 10 seconds.
So there's XML::Compile::Transport::SOAPHTTP which does that,but then I was trying to figure out how that relates to the main XML::Compile::WSDL11 when doing the actual call with

my $call = $wsdl->compileClient('GetStockPrice', ...);
# at "run-time", call as often as you want (fast)
my $answer = $call->(%request);

how does the XML::Compile::Transport::SOAPHTTP relates to this call?How should I use it?
eventually after sometime I used

my $trans = XML::Compile::Transport::SOAPHTTP
  ->new(timeout => 500, address => $wsdl->endPoint);
$wsdl->compileCalls(transport => $trans);
 
# alternatives for simple cases
$wsdl->compileAll('CALLS');
$wsdl->compileAll;
 
my $answer = $wsdl->call($myop, $request);

and not using compileClient.

but the point is, can I rely to something else than the documentation? Would introspection be useful in this case?
