It would be great to have some guidance to others in the future that need to figure out which the correct document/globalObject,scriptExecutionContext is the right one to use (though I don't have a great idea where to put this guidance).

Perhaps also remaining the non-prefixed ones to use Current/Entry/etc prefixes would help, since people would feel they need to understand the concept before picking.

Thanks for review!

Yeah, that is the plan. Having _current_ by default, for non-prefixed values, is prone to introducing incompatibilities.

For now I will add a spec link to both IDLAttributes.json and CodeGeneratorJS.pm; WHATWG editors did a great job explaining the concepts.

Sounds great. (The more we can use spec names in our code, the better in my book. I would love to see more done in this area, especially in the area of JSC functions that WebCore bindings have to interact with).
