Thank you!
The CachingCIncludeTransformer works properly not only in theory :)
I tested it (among other) with yout example from
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=4641
I think you can close the bug 4641.

Actually, problem lies in Source interface desing not in 
CachingCIncludeTransformer. Recenty Source design has been changed 
and in theory CachingCIncludeTransformer should work properly. 
Unfortunately I don't have time to check it at the moment. If You are 
in need please try current CVS version of Cocoon.
