Invocation: investigate kind of data to be represented in ProcID

...especially the extended attributes remain somewhat nebulous, since non of the prospective usages are close to being implemented right now. It seems, we'll get two distinct sources at construction time of the Node * additional qualifiers from the Library plug-in * internal flags or qualifiers provided by the `NodeBuilder` Another related concern seems to be generation of cache-keys, which however will ''consume'' the proc-hash generated by the ProcID, but not change the ID itself; cache-key generation is a tricky subject and was somewhat overlooked regarding the connection to the `BufferProvider`. Opened a new ticket #1292 as reminder for this issue.

+    <p>
+      Da Fall-1 am Wichtigsten ist, orientiert sich das Interface daran und reicht einfach die Collection der Vorg&#228;nger-Ports per Referenz heraus. Leider haben wir aber im Fall de ParamWeavingPattern gar keine Collection der Vorg&#228;nger-Ports, sondern nur eine direkte Referenz auf den Delegate des Proxy; und da es sich um einen einfachen Funktionsaufruf handelt, haben wir keinen Ort, an dem eine solche Collection hilfsweise konstruiert und abgelegt werden k&#246;nnte. Deshalb bleibt nur, entweder in dem Fall gar nichts zu liefern, d.h. zwei verschiedene Methoden zu bieten, oder eben die Rekursion auf das Delegate (das dann hoffentlich ein Manifold-Pattern ist und deshalb eine solche Collection hat)
