XBL requires namespace (therefore XML capable) UA's to work, where-as 
this one merely needs JS and the all-possible extension mechanism 
allowed with <link ...>

As well this does not bring with it the complications in XBL, such as 
DOM methods, etc.

 From my understanding its meant as a quick and easy addition to HTML, 
rather than a largely superior feature-rich extension to (as currently 
stands) SVG.
