Hi Fabien,

well that is a very interesting point you come to. I didn't think about this
possibility so far. It sounds like an approach, that could become a useful
fundamental concept to make lib/div more flexible: services that are mvc
themself. 

That is related to subcontrollers which do the same, but without doing it in
form of a service. With the last update I implemented the subcontroller
feature by adding 2 new parameters to the main function:

function main($input, $configurations, $context=NULL, $parameters=NULL) 

A lib/div specific service could be based on this directly, that takes this
four parameters. 

Also non lib/div specific services could also be done with lib/div. The
service (but not the user of the service) would need to prepare/customize
the parameters of main() to send all required input values to the service.

There is one limitation. The return value of such a service is always a
string.
