Correct.

Also, correct (I think)... although, I don't think we have a test case
for this at the moment.

>From my understanding, which includes Ben's most recent proposal, this
is the behavior of @instanceof:

1. Applies to @about or @src if either exist on the current
   element, @about takes precedence over @src.
2. Creates a new bnode if there is no @about or @src on the current
   element.

I'm talking about the new one that was just created for the local
@instanceof. @instanceof does not inherit anything, ever.

Correct!

We talked about Mark's most recent e-mail[1] and it deviates from the
understanding of the group
