Yes, I misread it. I guess that I'm missing something, as what it really 
says seems redundant nonsense to me.

Consider the given example:

The <span id="w3c">World Wide Web Consortium</span> (<abbr 
full="#w3c">W3C</abbr>) develops interoperable...

Where the attribute refers to the immediate context. This is what should 
be marked, but not when the abbreviation appears say five paragraphs 
later? Now I'm really confused :)

Perhaps we misunderstand each other here. I'm not advocating for a 
*must*, but for a *should*, as in RFC 2119.
