[css-content] Keyword 'document-url' is undefined

[SebastianZ]

The keyword document-url is included in the syntax of <content-list> in the CSS Generated Content Module Level 3, though there is no prose defining its meaning.

I think this was a hoped-for feature in the 2003 draft. Given that there appears to be no implementation interest, no mentions on www-style, and such things are easily done by JS, I'll remove it.
