[whatwg] Target Attribute Values

[Lachlan Hunt]

Hi,
   This is regarding the valid browsing context names, used for the 
target attribute [1].

Why is _blank still considered a conforming value?  On IRC, Hixie 
mentioned that there are some legitimate use cases, but didn't list any. 
  I've argued against popups many times before and heard many arguments 
for them, but I'm yet to hear of any legitimate use cases.  If there are 
any, what are they?

_new is also not specced, yet it is widely used and treated as a magic 
value like _blank in Firefox.  Maybe it should be specced the same as 
_blank.  However, IE, Opera and Safari didn't appear to treat it as 
such, so maybe it's not needed.
