ok - in that case I was way too naive with my thinking. I apologize.

I just wanted to add that this is a very important method for many
interactive applications. Think about maps/GIS, interactive graphics
editors, applications where you need to select elements to manipulate
them, etc

BTW: Jeff (codedread) let me know that he is working on a native
implementation (Webkit), not a Javascript shim as I was thinking.

So, hopefully, along with the implementation(s) ambiguous or missing parts
in the spec could be addded/clarified.
