1. A simple IMG without ALT, not linked nor used anywhere else: (Guess using filename from IMG-SRC URL, instead [IMAGE])
2. Button in pure link, that is with empty content: (Guess using directory of A-REF, not IMG-SRC, instead [LINK]. Using directory because 'index' is pretty useless...)
3. An IMG with ALT already set: and using this IMG again, but forgot to set ALT: (Guess using previous tag, retrieved from ALT_Registry)
4. Inline icon in non-pure link: Go to http://www.yahoo.com (Guess ALT="" because link content is not empty.)
5. Button in pure link: (Guess using link's content text from other occurence of link, retrieved from ALT_Registry)
The graphical horizontal ruler is an IMG and not a HR tag. (Guess "____" using ruler heuristic, based on size, variable width)
2. Special Counter IMG with width=0 & height=0: (Guess ALT="" because width=0 & height=0, instead [IMAGE])
