I would consider that an addition. But sure, proposals that change the  
range of applicability of these mechanisms would also be in scope. So  
if someone really wanted to propose allowing the rel attribute on  
<img> elements, that would be in scope (though in my opinion, it would  
be a silly idea).

While it's not not required for proposals to resemble to Namespaces in  
XML to be in scope, it is certainly permitted.

I think the chairs would consider proposing a specific solution to the  
issue after it is resolved to be equivalent to reopening this issue.  
Thus, we would generally only allow it based on new information that  
was not available at the time of the original decision.

Indeed, and that is what we're doing. Anyone who volunteers during  
that one-month period will get at least a month from the time they  
volunteer, and the chairs are likely to grant requests for reasonable  
extensions beyond that. My apologies if that wasn't clear.

If anyone thinks their proposal is complex enough to require extra  
time, they can ask the chairs for an extended deadline on the writing.
