::::::Sortname will just create a redlink for table entries that don't have Wikipedia articles, e.g. 
 {|class="wikitable sortable" 
 !Name 
 |- 
 | 
 |- 
 | 
 |} 
 ::::::However, we could also have the names unlinked, if we use {{Sortname|Pongo|Rafferty|nolink=1}}. Although I reckon that, in most cases, redlinking would be the way to go, per WP:REDLINK.   |
