"a whole language for handling events across the representation of layout"

While I agree block-linking seems like an odd way to implement the desired functionality, the idea that javascript (did you mean javascript?) is a more suitable alternative is dubious.

The concept of requiring an entire engine to enable linking from HTML elements just seems dirty, when it could be achieved so much more simply with a universal href tag. For starters, how would one define link targets?
