I think a better mechanism would be as follows (though I am not yet 
convinced that CSS should involve itself in link recognition).

Name:       link
Values:     [ none | <selector>? attr(<name>) ]
                 [ , <selector>? attr(<name>) ]*
Initial:    none
Applies to: all elements
Inherited:  no

The solitary 'none' means that this style sheet does not find any link 
here, although link recognition by other means is still possible.  In 
all other cases, the first item in the list determines whether and 
what the primary link is.  Thus, there may be no primary link while 
one or more secondary links exist:

blockquote { link: none, attr(cite) }

Would it be better to allow but ignore link properties in rules whose 
selectors include link pseudo-classes?  This would affect what is 
considered a valid style sheet.  Does this make a difference in 
implementation?
