Subject: Bill: question about cross-reference expansion

Title:
Trust Framework Provider Adoption Process (TFPAP) - Version 1.0.1
Bill, I was thinking about how this would work to "fully expand" all XDI addresses into "$ statements", i.e., into XDI statements consisting of all $words (plus the four GCS symbols and literals).
It's a cool idea, and for a one-segment statement like +a, it's easy.
+a
(+/a)
+/$has/a
It is also easy for (+a).
(+a)
$$/$has//+a
$$/$has//(+/a)
$$/$has//+/$has/a
But I got stuck trying to expand the statement +a+b.
+a+b
(+a/+b)
+a/$has/+b
(+/a)/$has/(+/b)
(+/$has/a)/$has/(+/$has/b)
At this point I don't know how to get rid of the parentheses and still make it a valid XDI statement.
Ideas?
