[whatwg] Target Attribute Values

[Benjamin Hawkes-Lewis]

It's worth speculating how this would work in an alternate universe 
where authors cared more about usability and user agents made more 
intelligent use of HTML. Most of the usecases mentioned involve 
differentiating sets of links, and deciding how they should be treated 
on behalf of users. HTML includes many ways of classifying anchor links 
into groups (rel/rev, type, hreflang, class), such that users really 
ought to be able to make such decisions for themselves. In the 
mirrorverse, user agents would come with customizable behaviours for 
classifications such as:

rel="external"

rel="help"

type="application/pdf"
