Actually its mapped to the SxFolderRSS "WOComponent" (pageName)  
(which implies special initialization and context).

I think you can also map to arbitary Objective-C classes (with  
'class'? ;-)

Hm, no. "/" is the delimiter for the object traversal path (which can  
lead to callable objects).
Sometimes a file extension gets stripped (eg Calendar/12345 and  
Calendar/12345.ics will both lead to the same object), though not in  
this case.

The /rss is reachable because of the mapping in the RSS bundle you  
show above. "Notes.rss" is explicitly mapped in the ZSProjects bundle.

Good question, I'm not sure why we have both
   http://{server}/zidestore/so/{username}/Projects/{projectNumber}/ 
Notes.rss
and
   http://{server}/zidestore/so/{username}/Projects/{projectNumber}/ 
Notes/rss

Most likely we had the first one first and later we added the  
"generic" rss method which works on all SxFolder objects. So this  
might need a bit of refactoring.

Even if we do want to support Notes.rss for convenience, I think I  
would have implemented that as a simple alias for Notes/rss.
