Good questions.

Bonus points to anybody who phrases them in the form of test cases.

(what's an alias, by the way? Do you mean prefix declaration? or
@keywords declaration? or both?)

I don't believe so.

Well, technically, I suppose n3.n3 does answer these questions,
and TimBL occasionally says it's definitive, but I think he
still considers the scope of prefix and keywords declarations
something of an open issue.

Hmm... we've strayed a bit from the "string escapes" bug.
I suppose if the scope of prefix and keywords is open,
it deserves a place in the issues list,
i.e. http://www.w3.org/2000/10/swap/admin/openBugs.html

I suppose "2004-06-10T21:22:46Z raised: RFE: formal N3 grammar"
covers it, though it doesn't isolate the issue very well.
