Luca I have the same type of need to produce SVG for barcodes. I have a String code as parameter, and an external java module to produce graphic informations. I will do it with an Action obtaining these informations as java objects, a generator generating corresponding XML datas (<svg>...</svg>) . A Stylesheet transform it. But i'm not expert, surely there are other possibilities.
