Re: [css3-gcpm] No need to call out attr() in bookmark-label and bookmark-target

Right, we no longer need to do what CSS 2.1 does -- e.g., here:

A relief.

I've removed it from the editor's draft:

I can see that the cue-based approach to functional arguments make
some sense; replacing "," with " as " could possible make things more
readable. Taking the type out of the parethesis may be even better:

    bookmark-label: attr(title) as string

I'm not sure it scales, though. Consider this example, which people
have been writing for some years:

    a::after { content: "(see page " target-counter(attr(href, url), page, decimal) ")" }

which could become:

    a::after { content: "(see page " target-counter(attr(href as url) of page as decimal) ")" }

or perhaps:

    a::after { content: "(see page " target-counter(attr(href) as url, of (page) as decimal) ")" }

It suddenly doesn't look as good anymore. Hmm.
