I totally agree with InputModules - and we discussed this already some weeks
ago in the thread about the InputModules Interface. If you look at it, this
interface was not directly intended for the use in the sitemap. So we
should fix this (already discussed, too) as well.

Perhaps there is a better name for inputmodules but as I don't want
to start a new thread about "what is the best name". I would like

Ok, now to the sources... :) - the sources are a configuration on the
application level, you once define which protocols you can use in your
application and that's it. So, the cocoon.xconf is in my eyes the
right place. Furthermore I see some technical problems with declaring
a source in the sitemap.

Now, if you follow this road, that every important aspect has to
be in the sitemap, you can add the xsp logicsheet definitions there
as well, because in the sitemap they are more visible for XSP
developers. And so on.

So I think we should leave them where they are.
