Your research regarding 'views' is right. We don't use it anymore; 
instead, it is recommended to use standard Zope traversal. The above 
line is almost correct in that aspect, it would be better with the view 
traversal indicators (@@):

   context/@@standard_macros/page

Otherwise Stephan's right, Zope X3 is not about TTW development but 
filesystem-based code.
