Hello,
I know how to add a new namespace, that's OK. But I'd like this namespace behave like categories : if I call MyNamespace:Foobar, if this page doesn't exist, I'd like to display an automatically generated content, for instance <my_extension>blabla</my_extension>
I don't want to display a list of articles as if it were a category, I'd like to know the way to generate automatic content for non-existing (or all) pages in this namespace.
