Ah, got it. I think I like that though it may be pushing the bounds of
'taxonomy' :-)

Got it. I guess my question is do we distinguish between attributes
whose values are 'objects' in their own right versus those whose
values are literals ...

Got it. Sounds like we really want a wiki page for documenting all
this useful conceptual stuff (as there is quite a bit of thinking
going on here!)

Got it. That does not sound a bad idea but surely:

/account/

is more useful than /session/ (and could replace it with
/account/login and /account/logout in addition to the the general
profile management at /account/{userid})
