[Radiant] SEO in Radiant

[Matt Bauman]

The only SEO feature I could see being nice to implement on the back- 
end (or extension) side of things would be the ability to easily add  
a "keywords" string in addition to the slug and title.  And then it  
would be slick for Radiant to automatically dig through all of the  
parent pages, appending the strings together when you call the tag  
<r:page:keywords />.

Does the page attributes extension allow for something of the sort?   
I haven't checked that extension out yet.  Maybe I'll look into  
adding such a tag myself if it doesn't yet exist...
