+      zun&#228;chst wollte ich ja einen Routing-Descriptor, um damit nochemal eine zweite Indirektion / Flexibilisierung gegen&#252;ber dem InvocationAdapter zu machen. Dann hat sich aber die Bedeutung des Invocation-Adapters so verschoben, da&#223; ein Teil seiner Rolle mit der FeedManifold verschmolzen ist, daf&#252;r aber ein rigideres Belegungsschema dem Binding-Functor abverlangt wird. Damit wurde explizite oder schematische Routing-Info eigentlich irrelevant, und ich habe sie durch direkte Referenzen ersetzt. <b>Und das ist nun das Problem</b>.
