jordanjay29 This stuff isn't something that involves W3C, also rel=nofollow
was introduced by Google in the past without the W3C. This changes are compliant with all browsers, because this changes aren't related to W3C.
How to explain... Google only uses a value, they don't change the W3C specification.
<a rel="value">
We only modify the "value"
and i maybe needs the value house
and another webmaster maybe needs the value hamster
, this is nothing related to W3C, is like a variable.
