WRT 1) that seems like a bad idea. anchor="" allows making statements 
about sub resources, and there should be exactly one way to do that (so 
it can be dealt with in a generic parser).

Furthermore, what do you mean by "dynamic scope"?

Option 2) sounds ok, but I'm not sure why it would only be advisory?
