XDI X3 format

Hi Bill !

I am in the process of learning a bit about XDI, and while reading through various material I came across your X3 notation, which looks wonderful. However, in different documents it looks slightly different.

(This looks very compact..)

(Here subjects, predicates, objects and literals are all on separate lines.)

Could you help me out to understand which one is your most recent idea of this format? I assume it's the second, since it is the more recent document, but I thought I'd ask you since you invented it!

all the best,
Markus
