[seam-dev] Pages.xml and extensibility

When pages.xml gets moved to seam 3 would it be possible to allow it to be extended using xml namespaces, and provide some kind of API for allowing extensions access to this information? I can think of a few different uses, from custom security implementations, to storing general page metadata. I also think that this would allow from configuration of beans on a per page basis, e.g: <pages> <page view-id="/*" > <xns:beans> <myapp:Foo> <!-- foo's config --> </myapp:Foo> </xns:beans> </page> <page view-id="/admin/" > <xns:beans> <myapp:AdminFoo> <!-- admin foo's config --> </myapp:AdminFoo> </xns:beans> </page> </pages> I have a pretty good idea how to implement this, i would add a custom qualifier to each bean and then generate a producer method that picks the correct one. Does this sound like a good idea? Stuart
