RE: [xri] Top Ten XRI Requirements

Hi Peter,

Maybe I'm miss-interpreting this but "delegation" does not imply
"hierarchy" but just a directed graph (from which a tree is a notorious
example). Interpreted like this I'm fine with the text.

I am not certain that the "federation" decsription is quite in line with
the industries (recent) understanding of the term. Here, as stated, it
implies a heirarchical relationship, but federations (as defined in my
mind based on the Liberty Alliance activities and working definitions),
is more closely related to peer-to-peer.  that si to say:

Unlimited Federation: allows for the identifier authority to construct
arbitrary associations with other authorities identifiers.

I think this is more consitant with want is reflected, then, in items 5
and 7
