While implementing this some questions arisen:
1. What about error handling? Should we provide some mechanism for
passing exception from one servlet to the another? Or maybe just a error
code and string message is sufficient?
Since it is one stacktrace if you call an internal servlet backed up by a
SitemapServlet, you can simply pass on the ProcessingException and not
serializing an error page into the stream between both servlets. In the old
blocks-fw-impl there is a patch that does exactly that, it re-throws the
exception: https://issues.apache.org/jira/browse/COCOON-1954
BTW: The following problems have been issues with the blocks-fw I have
encountered during real-world usage, especially when using cforms in the
"backend"-servlet. We should check those in the new implementation.
