Google authorship syntax, plus no follow

[scanlin]

I have seen two forms of rel=author syntax. Are they both valid?

(1)

(2)

Second, does 'no follow' take away authorship? Is there any point in doing rel=author for a link that is rel=no follow? Like this:

I'm not sure about the syntax question, but I would think the nofollow would have a negative effect, why would you want to nofollow a link you want Google to follow to make the association?

It's not my choice to no follow the author credit; it's a policy on another site where I guest blog. I'm just wondering if they're causing me not to get authorship credit by adding the no follow.

My goodness ! they atleast they can give a dofollow link ! this is bad !

As Irving told that no-follow will be a problem. link nofollow will be simple no backlink, but the authorship nofollow is new ! consider that advice of the expert one !

we sometimes make the link no-follow, but not for the author google plus !
