 You can add interest selectors. For example, this uses 1 to select the "rightmost" child
 (latest version).
-ndn:/ndn/ucla.edu/apps/ndn-js-test/hello.txt?ndn.ChildSelector=1&key=value#ref
+(ndn:/ndn/ucla.edu/apps/ndn-js-test/hello.txt?ndn.ChildSelector=1&key=value#ref)
 
 The browser loads the latest version and changes the address to:
-ndn:/ndn/ucla.edu/apps/ndn-js-test/hello.txt/%FD%05%0B%16z%22%D1?key=value#ref
+(ndn:/ndn/ucla.edu/apps/ndn-js-test/hello.txt/%FD%05%0B%16z%22%D1?key=value#ref)
 
 The child selector was used and removed. Note that the other non-ndn query values and 
 ref "?key=value#ref" are still present, in case they are needed by the web application.
