Thanks for doing this. I'll note off the top that I woke up last night 
at 3 a.m. and had a vision of what the diagram could look like, with 
all the time-flow steps and taking into account the Entities (real and 
virtual) of: Subject, Holder, Issuer, Repository, and Relaying Party, 
and the Documents (fixed statements) of Claim and Credential.

This took half an hour to take shape in my mind, and then I dictated a 
description of it. I'm committed to making my imagined version of the 
diagram myself (I've done a lot of computer technical drawing in my 
life, but none for several years, and would enjoy the challenge at 
this point.)

About yours: it's nothing like mine at all. :-)

Although technically interesting to have the diagram change and show 
steps in sequence like that, with due respect, I found it just as 
confusing. And I don't know if it's wise to introduce that technology 
anyway for a mission-critical diagram -- it may not work for some people.

If I may, I'll make mine and send a link. Would a Drop-box link work? 
Or is sending as an attachment better?

And I can do any common graphic file format -- png, svg, jpg, pdf, 
etc. If you have a preference let me know.

I'm going to transcribe my last-night's dictation today and probably 
start making the diagram, but I might as well delay sending until I 
get the results of the voting for terminology, which I should use in it.
