Granularity

In some books I've seen sections that start with the first (say) four words in
small caps.  Is there any plan for this capability in CSS?  Something like

	p:first-words(4) { font-variant: small-caps }

Or, supposing you want to make sure the small cap words only appear on the first
line (instead of running into the second line on a resize), something like

	p:first-line:first-words(4) { ... }

And what about more granular specifications, like "the 2nd through the 5th
letters of the 6th word in the 8th paragraph?
