I 
think he means "scoped values". From your spec:
 
     audience="programmer/database 
programmer/Java programmer/Web"
 
I'm 
surprised to see this in the spec too, since I was not aware that there is 
significant demand for this. Maybe I missed the discussion.

This document describes negative 
  values:

http://www.oasis-open.org/committees/download.php/17329/IssueNumber20.ht
ml

It 
  isn't explicit about the semantics of them. For example, it implies
that 
  negative and positive values can be combined in a single 
  attribute
(otherwise why say that the NOT operator only applies to a 
  single
value). But I would have thought that a negation of value A 
  implies
value B by definition. Therefore explicitly stating value B 
  is
redundant.

audience="NOT paul"

Means everybody but paul. 
  Therefore saying "everybody but paul plus
janice" is redundant. In 
  programming language terms:

If Audience!=paul OR 
  audience=janice

Although I am a fan of the goals of this feature, I am 
  not convinced
that we can work out the details in the time we have. Plus I 
  think that
it is a bit of scope creep beyond what the TC agreed to. The 
  same goes
for the scope attribute.
