Hello Burak, thank you for the reply.

My aim is to propose a built-in method to accomplish this common and simple task that, IMHO, shouln't require the use of extra code for legibility's sake.

Anyway the whole Spyne framework is very interesting, thank you for having shared that!
Probably it's going to be useful for a project of mine :)

Have a nice day,
Francesco
