What's the document associated with xhr? Is it w1.document,

I don't have a <dfn> for it, but
http://dev.w3.org/2006/webapi/WebIDL/#dfn-initial-object says that each
global environment has a set of interface objects, and in
http://dev.w3.org/2006/webapi/WebIDL/#es-platform-objects I use the term
"associated with", but again not wrapped in a <dfn>.
Sure. And the latter section says:
It is the responsibility of specifications using Web IDL to state
which global environment (or, by proxy, which global object) each
platform object is associated with.
And my point is that the XHR spec doesn't state that. Stating that the
return value is associated with the same global environment as the
constructor that was used to create it would do the trick.
On the other hand, maybe that should just be in WebIDL? Are there use
cases for constructors which create platform objects associated with a
different global than the constructor itself?
I believe some things in the HTML spec uses the entry script, at least for
the purpose of choosing origin or base URL. For instance: WebSocket,
Worker.
