I have already thought of that but the problemis that here the "source" is the
generator name. Do you know how should I lookup a generator, setup it properly
(to support map:parameter for example) and than invoke it? with everything
done not to break sitemap reloading (new generators may come in place, old may
be deleted), caching and other stuff I cannot really comprehend :)
AFAIU this is exactly a small part of a TreeProcessor functionality and the
TreeProcessor itself is really complicated. I'am afraid I would have to
rewrite/duplicate a lot of code.
