 =item * B<condenseParts>: A flag. If yes (default), if all parts of the problem have the same status and that status is Nothing Set, Correct, or Network Failure, then only one line will be displayed for that resource anyhow. If no, all parts will always be displayed. If showParts is 0, this is ignored.  =item * B<condenseParts>: A flag.

 =item * B<jumpCount>: A string identifying the URL to place the anchor 'curloc' at. Default to no anchor at all. It is the responsibility of the renderer user to ensure that the #curloc is in the URL. By default, determined through the use of the ENV{} 'jump' and 'jumpType' information.  =item * B<jumpCount>: A string identifying the URL to place the anchor 'curloc' at. Default to no anchor at all. It is the responsibility of the renderer user to ensure that the #curloc is in the URL. By default, determined through the use of the ENV{} 'jump' information, and should normally "just work" correctly.
   
 =item * B<here>: A Symb identifying where to place the 'here' marker. Default empty, which means no marker.  =item * B<here>: A Symb identifying where to place the 'here' marker. Default empty, which means no marker.
